    Before RILEY, SMITH, and COLLOTON, Circuit Judges.

    SMITH, Circuit Judge.
    Harold Stults was indicted for possessing one or more photographs and other
    matter containing images of child pornography, in violation of 18 U.S.C.
    § 2252(a)(4)(B). The indictment further charged that Stults possessed child
    pornography after having previously been convicted for attempted sexual assault of
    a child in the second degree, a predicate offense requiring the imposition of a ten-year
    mandatory minimum sentence pursuant to 18 U.S.C. § 2252(b)(2). Stults initially
    pleaded not guilty to the indictment but, after the district court1 denied his motion to
    1
    The Honorable Joseph F. Bataillon, Chief Judge, United States District Court
    for the District of Nebraska.
    suppress evidence obtained from a court-authorized search warrant, Stults
    conditionally pleaded guilty. The district court sentenced Stults to 144 months'
    imprisonment, followed by a lifetime of supervised release.
    Stults appeals, arguing that: (1) his Fourth Amendment rights were violated
    because law enforcement conducted an illegal search of his computer without a
    warrant or a valid exception to the warrant requirement; (2) the affidavit submitted in
    support of the search warrant was the fruit of the illegal search and was insufficient
    to establish probable cause; (3) his prior conviction for attempted sexual assault in the
    second degree is not a predicate offense that triggers the ten-year mandatory minimum
    sentence under 18 U.S.C. § 2252(b)(2); (4) the district court erred in applying a five-
    level enhancement for distribution for receipt of a thing of value under U.S.S.G. §
    2G2.2(b)(3)(B); (5) his 144-month sentence is unreasonable because it is greater than
    necessary to promote the goals of 18 U.S.C. § 3553(a); and (6) four of the special
    conditions of supervised release imposed by the district court constitute a deprivation
    of liberty more burdensome than necessary to serve federal sentencing goals. We now
    affirm the judgment of the district court.
    I. Background
    Special Agent Brent Morral of the Department of Homeland Security, Bureau
    of Immigration and Custom Enforcement, applied for a federal search warrant for
    8042 Maywood Street, Omaha, Nebraska—Stults's residence. The application and
    affidavit requested permission to seize computers, computer files, and other
    documents pertaining to child pornography, in violation of 18 U.S.C. §§ 2252 and
    2252A. The application and affidavit also described a method of communication
    known as peer-to-peer ("P2P") computer file sharing that utilizes the Internet to allow
    individuals to share data contained in computer files. P2P file sharing can be used to
    share child pornography and trade digital files containing images of child
    pornography. Using the P2P file-sharing method, when two users actively participate,
    files may be sent from one user's computer to another user's computer without the
    -2-
    permission or knowledge of the other user. It is not possible for one user to send or
    upload data, including child pornography, to another user or his computer without that
    user's active participation.
    In the search warrant application and affidavit, Agent Morral recounted his
    experience and training in computer usage and investigation of child pornography
    cases. Additionally, he incorporated details of an investigation by Special Agent
    Joseph Cecchini of the Federal Bureau of Investigation (FBI) who used a P2P file-
    sharing program called "LimeWire." Agent Cecchini, in an online undercover
    capacity, conducted a search looking for users accessing known child pornography
    sites. After signing on to LimeWire, he entered the search term "PTHC" ("preteen
    hard core"), a term associated with images of child pornography. Agent Cecchini
    received responses from Internet Protocol (IP) address 24.252.31.129. Cecchini
    connected with the computer using this IP address and viewed a list of files available
    from the computer for sharing. He downloaded 14 files from the computer that seemed
    consistent with child pornography. The file names included: (1) Photo by Carl—pedo
    incest 13yr girl f****d by daddy (2) Pedo 13Yo Haley.jpg; (3) fdsa7-10 girl and 6yo
    boy pedo R%40 ygold hyssfan lolitaguy . . . baby shivid.mpg; (4) 5yo Girl Raped By
    Mommy; and (5) 8yo Preteen Girl Raped by 16yo Brother. Among the 14 files
    downloaded from the computer, Agent Cecchini observed a nude prepubescent female
    being vaginally penetrated by a young male's penis; a nude prepubescent female with
    an adult penis touching her vaginal area; and a nude prepubescent female with her
    underwear down and her legs spread.
    Pursuant to a subpoena, Cox Communications, the Internet provider, identified
    the subscriber using the IP address 24.252.31.129 as "Harold Stults, 8042 Maywood
    Street, Omaha, Nebraska." A public records check using LexisNexis, a postal service
    mail delivery check, and a motor vehicle registration check all confirmed that a
    "Harold Stults" was the resident of 8042 Maywood Street.
    -3-
    Agent Morral received the warrant to search Stults's residence, and, when the
    search warrant was executed, agents seized hard drive towers, computer storage
    media, and various documents from the residence. Forensic analysis revealed 60
    videos and numerous images of child pornography on Stults's computer. The files
    were stored on the C:drive and on compact disks. The videos and images were sent
    to the National Center for Missing and Exploited Children (NCMEC). NCMEC
    identified one movie and 71 image files as portraying known child victims. Many of
    the images involved prepubescent children. Two of the videos portrayed sadistic or
    masochistic conduct or depictions of violence. One video portrayed an apparent
    ten-year-old female whose hands and legs were bound providing oral sex to an adult
    male. A second video portrayed a 12-year-old girl bound in red rope being digitally
    penetrated.
    When confronted by law enforcement, Stults admitted to using LimeWire to
    download music and pornography; using the search terms "pthc," "young girls," and
    "pre teen" to download child pornography; keeping the pornography in his shared
    folders; and recently viewing child pornography a few days earlier.
    Stults was charged with one count of possession of child pornography, in
    violation of 18 U.S.C. § 2252(a)(4)(B). Because he had previously been convicted in
    November 1993 of attempted sexual assault of a child, he was subject to a ten-year
    mandatory minimum and 20-year maximum sentence pursuant to 18 U.S.C.
    § 2252(b)(2).2
    2
    According to the presentence investigation report (PSR), the attempted sexual
    assault conviction involved Stults's 11-year-old niece. The niece reported that Stults
    carried her into his bedroom, removed her clothes, and laid her on the floor. She
    reported that he then began to fondle her breasts, rub her vaginal area with his hands,
    and place his mouth on her vaginal area. She also said that he had rubbed his penis
    against her vagina and stopped when her mother knocked on the door. Stults was
    convicted in the district court of Douglas County, Nebraska, for attempted sexual
    assault. He received a sentence of two to three years' imprisonment.
    -4-
    Stults filed a motion to suppress all evidence obtained as a result of the
    execution of the federal search warrant at his residence. The initial motion to suppress
    challenged the validity of the warrant's issuance. Stults contended that the affidavit
    failed to set forth sufficient facts and circumstances to justify a belief that evidence
    of a crime would be located at Stults's residence. Stults later supplemented his motion,
    alleging that the federal search warrant was obtained following an illegal P2P search
    of his home computer. According to Stults, Agent Cecchini conducted a warrantless
    search when he viewed the files from IP address 24.252.31.129, Stults's IP address,
    after Agent Cecchini launched the P2P program searching for child pornography.
    Stults argued that Agent Cecchini was able to determine the contents of Stults's
    computer, retrieve files from his computer, and view those files at a distant location
    without Stults's consent. Stults asserted that without the information from the P2P
    search information, the search warrant for his premises or computer files could not
    have been supported by probable cause.
    The magistrate judge recommended to the district court that it deny Stults's
    motion to suppress, finding that sufficient probable cause existed to believe that the
    items sought in the application and affidavit would be found on the premises to be
    searched. In the alterative, the magistrate judge found that the good-faith exception
    of United States v. Leon, 
    468 U.S. 897
    (1984), would apply, allowing for the
    admissibility of the evidence seized.
    The district court adopted the magistrate judge's report and recommendation
    denying the motion to suppress. First, the district court found that "[t]here is no
    Additionally, Stults had previously been sentenced to a six to ten-year term of
    imprisonment in June 1998 for burglary. According to the arrest report, Stults was
    found shirtless in the basement bedroom of a residence. Two pairs of adult and one
    pair of children's underwear were found in his pockets. He admitted to entering the
    basement and taking two pairs of ladies' underwear. He claimed to have received the
    child's underwear at a party that he had attended earlier.
    -5-
    reasonable expectation of privacy in computer files that are accessible to users of a
    computer network." United States v. Stults, 
    2007 WL 4284721
    , at *1 (D. Neb. Dec.
    3, 2007) (unpublished). As a result, the district court "agree[d] with the magistrate's
    assessment that the warrantless downloading of files from defendant's computer by
    law enforcement officers did not implicate Fourth Amendment concerns." 
    Id. The district
    court also reviewed the search warrant and found that it contained probable
    cause to support the search. 
    Id. at *2.
    Furthermore, the court found that even if the
    affidavit was not sufficient to establish probable cause, "there has been no showing
    that any of these exceptions to the operation of Leon apply to this case." 
    Id. Thereafter, Stults
    entered a conditional plea of guilty. The conditional plea
    reserved the right to appeal the adverse decision of the district court denying the
    motion to suppress.
    The United States Probation Office prepared a PSR. The PSR calculated a base
    offense level of 18. The PSR stated that the following enhancements applied: (1) a
    two-level increase for material depicting prepubescent minors; (2) a five-level
    increase for distribution for a thing of value but not for pecuniary gain; (3) a four-level
    increase for material that portrays sadistic or masochistic images; (4) a two-level
    increase for use of a computer; and (5) a five-level increase for possessing more than
    600 images. The enhancements produced an adjusted offense level of 36. After
    subtracting three levels for acceptance of responsibility, the PSR reported a total
    offense level of 33. Stults's seven criminal history points placed him in a criminal
    history category IV. At a total offense level 33 and a criminal history category IV,
    Stults's Guidelines range was 188 to 235 months.
    Prior to sentencing, Stults objected to the mandatory minimum sentence,
    arguing that his plea of nolo contendere failed to establish that the attempted sexual
    assault on a child was a conviction relating to aggravated sexual abuse, sexual abuse,
    or abusive sexual conduct. Second, Stults objected to the five-level enhancement for
    -6-
    distribution in exchange for a thing of value and to the assessment of a two-level
    enhancement for use of a computer. Finally, he requested a variance from the
    Guidelines, arguing that the enhancements should be disregarded because they were
    not the result of empirical research by the United States Sentencing Commission.
    The district court found that the PSR properly calculated Stults's Guidelines
    range and overruled his objections. It sentenced Stults to 144 months' imprisonment,
    followed by a lifetime of supervised release. The district court also imposed a number
    of special conditions of Stults's supervised release. Stults objected to the following
    special conditions:
    4.     The defendant shall have no contact, nor reside with children
    under the age of 18, including his own children, unless approved
    in advance and in writing by the probation officer in consultation
    with the treatment providers. The defendant must report all
    incidental contact with children to the probation officer and
    treatment provider.
    5.     The defendant shall not access or come within 500 feet of schools,
    school yards, parks, arcades, playgrounds, amusement parks, or
    other places used primarily by children under the age of 18 unless
    approved in advance and in writing by the probation officer.
    ***
    7.     The defendant shall not access, view or possess any pornographic
    sexually oriented or sexually stimulating materials, including
    visual, auditory, telephonic, or electronic media, computer
    programs or services. The defendant shall not patronize any place
    where such material or entertainment is available without express
    permission of the United States Probation Office.
    ***
    -7-
    12.    Except for purposes of his employment, the defendant is
    prohibited from using or having access to any electronic media
    that has internet service or photography capability without express
    permission from United States Probation Office. The defendant
    will sign any and all releases of information as it relates to cell
    phone carriers.
    The district court overruled Stults's objections to the supervised release conditions.
    II. Discussion
    Stults raises six arguments on appeal. First, he argues that his Fourth
    Amendment rights were violated because law enforcement conducted an illegal search
    of his computer without a warrant or a valid exception to the warrant requirement.
    Second, he asserts that the affidavit submitted in support of the search warrant was the
    fruit of the illegal search and was insufficient to establish probable cause. Third, he
    contends that his prior conviction for attempted sexual assault in the second degree
    is not a predicate offense that triggers the ten-year mandatory minimum sentence
    under 18 U.S.C. § 2252(b)(2). Fourth, he maintains that the district court erred in
    applying a five-level enhancement for distribution for receipt of a thing of value under
    U.S.S.G. § 2G2.2(b)(3)(B). Fifth, he argues that his 144-month sentence is
    unreasonable because it is greater than necessary to promote the goals of 18 U.S.C.
    § 3553(a). Finally, he contends that four of the special conditions of supervised
    released imposed by the district court constitute a deprivation of liberty more
    burdensome than necessary to serve federal sentencing goals.
    A. Legality of Search of Stults's Computer
    Stults first argues that his Fourth Amendment rights were violated when the
    government conducted a warrantless search of his home computer.
    In response, the government asserts that the district court properly denied
    Stults's motion to suppress because Stults' use of LimeWire, a P2P file-sharing
    -8-
    network, belies a reasonable expectation of privacy in the files searched; therefore, the
    Fourth Amendment is not implicated when a law enforcement officer browses or
    downloads files from a computer that is sharing files with other networks on a file-
    sharing network.
    "We review the district court's factual determinations in support of its denial of
    a motion to suppress for clear error and its legal conclusions de novo." United States
    v. Clarke, 
    564 F.3d 949
    , 958 (8th Cir. 2009) (internal quotations and citations
    omitted). "We must affirm an order denying a motion to suppress unless the decision
    is unsupported by substantial evidence, is based on an erroneous view of the
    applicable law, or in light of the entire record, we are left with a firm and definite
    conviction that a mistake has been made." 
    Id. (internal quotations
    and citations
    omitted).
    "When moving to suppress evidence on the basis of an alleged unreasonable
    search, the defendant has the burden of showing a legitimate expectation of privacy
    in the area searched." United States v. James, 
    534 F.3d 868
    , 872 (8th Cir. 2008)
    (internal quotations and citation omitted). "Whether a defendant has a constitutionally
    protected expectation of privacy involves a two-part inquiry—the defendant must
    show that (1) he has a reasonable expectation of privacy in the areas searched or the
    items seized, and (2) society is prepared to accept the expectation of privacy as
    objectively reasonable." 
    Id. at 872–73
    (internal quotations and citation omitted). Here,
    we must decide whether Stults had both a subjective and objectively reasonable
    expectation of privacy in files accessed through Stults's installation and use of
    LimeWire, P2P file-sharing software.
    "LimeWire is a peer-to-peer file sharing application that connects users who
    wish to share data files with one another." United States v. Lewis, 
    554 F.3d 208
    , 211
    (1st Cir. 2009). It is "indifferent to the nature of the data-images or text or music or
    video or software. [It is] equally indifferent to the legal status of the data-public-
    -9-
    domain or copyrighted or contraband." 
    Id. "LimeWire combines
    two functions: the
    ability to search for and download files from other users, and the ability to make files
    on one's own computer available to other users." 
    Id. When a
    user wants to download
    files from other users, he "launches LimeWire and inputs a search term or terms. The
    application then seeks matches for those terms in the file names and descriptions of
    all files designated for sharing on all computers then running the LimeWire
    application . . . ." 
    Id. LimeWire will
    then "display[] a list of file names that match the
    search terms, and the user can select one or more of those to begin downloading the
    files." 
    Id. Several federal
    courts have rejected the argument that an individual has a
    reasonable expectation of privacy in his or her personal computer when file-sharing
    software, such as LimeWire, is installed. See, e.g., United States v. Ganoe, 
    538 F.3d 1117
    , 1127 (9th Cir. 2008) (holding that the defendant lacked a reasonable expectation
    of privacy in the downloaded files stored on his computer, meaning that an agent's use
    of a file-sharing software program to access child pornography files on the computer
    did not violate the defendant's Fourth Amendment rights); United States v. Perrine,
    
    518 F.3d 1196
    , 1205 (10th Cir. 2008) (holding that defendant had no expectation of
    privacy in government's acquisition of his subscriber information, including his IP
    address and name from third-party service providers, where the defendant voluntarily
    transmitted such information to Internet providers and enabled P2P file sharing on his
    computer, which permitted anyone with Internet access the ability to enter his
    computer and access certain folders); United States v. Barrows, 
    481 F.3d 1246
    , 1249
    (10th Cir. 2007) ("[The defendant] claims that he invited no one to use his computer
    and therefore expected its contents to remain private. Yet he surely contemplated at
    least some third-party access: he knowingly networked his machine to the city
    computer for the express purpose of sharing files."); United States v. Brese, No.
    CR-08-52-D, 
    2008 WL 1376269
    , at *2 (W.D. Okla. April 9, 2008) (unpublished)
    ("The Court finds that, notwithstanding any subjective expectation that Defendant
    may have had in the privacy of his computer, it was not reasonable for him to expect
    -10-
    privacy in files that were accessible to anyone else with LimeWire (or compatible)
    software and an internet connection."); United States v. Borowy, 
    577 F. Supp. 2d 1133
    , 1136 (D. Nev. 2008) ("In this case, [the defendant] did not have a legitimate
    expectation of privacy in files he made available to others using P2P software.").
    We hold that Stults had no reasonable expectation of privacy in files that the
    FBI retrieved from his personal computer where Stults admittedly installed and used
    LimeWire to make his files accessible to others for file sharing. One who gives his
    house keys to all of his friends who request them should not be surprised should some
    of them open the door without knocking. As a result, "[a]lthough as a general matter
    an individual has an objectively reasonable expectation of privacy in his personal
    computer, we fail to see how this expectation can survive [Stults's] decision to install
    and use file-sharing software, thereby opening his computer to anyone else with the
    same freely available program." 
    Ganoe, 538 F.3d at 1127
    (internal citation omitted).
    Even if we assumed that Stults "did not know that others would be able to access files
    stored on his own computer," Stults did know that "he had file-sharing software on his
    computer; indeed, he admitted that he used it—he says to get music [and to download
    pornography]." 
    Id. As a
    result, Stults "opened up his download folder to the world,
    including Agent [Cecchini]." 
    Id. "Having failed
    to demonstrate an expectation of
    privacy that society is prepared to accept as reasonable, [Stults] cannot invoke the
    protections of the Fourth Amendment." 
    Id. B. Probable
    Cause To Support Search Warrant
    Stults next argues that the affidavit submitted by law enforcement in support
    of the application for a search warrant was lacking in probable cause and that the Leon
    good-faith exception does not apply.
    In response, the government contends that Stults's facial validity challenge to
    the warrant fails because law enforcement agents were able to download child
    pornography from Stults's computer and the affidavit recounted this information,
    thereby providing sufficient probable cause for the issuance of the warrant.
    -11-
    "To be valid under the Fourth Amendment, a search warrant must be supported
    by a showing of probable cause." United States v. Wallace, 
    550 F.3d 729
    , 732 (8th
    Cir. 2008) (internal quotations and citation omitted). "Probable cause exists when
    there is a fair probability that contraband or evidence of a crime will be found in a
    particular place." United States v. Palega, 
    556 F.3d 709
    , 714 (8th Cir. 2009) (internal
    quotations and citations omitted)."Whether a search warrant is supported by probable
    cause is determined by the totality of the circumstances; resolution of the question by
    an issuing judge should be paid great deference by reviewing courts." United States
    v. Kattaria, 
    553 F.3d 1171
    , 1175 (8th Cir. 2009) (internal quotations and citations
    omitted). Our duty "is to ensure that the issuing judge had a substantial basis for
    concluding that probable cause existed." 
    Id. (internal quotations
    and citations
    omitted). "Where there is no evidentiary hearing before the magistrate judge, the
    probable cause determination must be based upon only that information which is
    found within the four corners of the affidavit." United States v. Olvey, 
    437 F.3d 804
    ,
    807 (8th Cir. 2006) (internal quotations and citation omitted).
    Here, the magistrate judge found that the application and affidavit: (1)
    "described a method of communication known as peer-to-peer (P2P) computer file
    sharing using the worldwide Internet"; (2) "described how individuals wishing to
    share child pornography use the P2P method to share and trade digital files containing
    images of child pornography"; (3) "described Agent Morral's experience and training
    in computer usage and investigation of child pornography cases"; (4) "incorporated
    details of an investigation by [Agent Cecchini] . . . who accessed a P2P file designated
    Lime[W]ire" and "conducted a search looking for users accessing known child
    pornography sites; (5) stated that an IP address traced to Stults was identified as
    accessing child pornography sites; and (6) recounted that shared files from Stults's
    computer were downloaded and reviewed and were identified as containing
    "numerous images of child pornography." United States v. Stults, No. 8:07-CR-199,
    
    2007 WL 3275129
    , at *2 (D. Neb. Nov. 2, 2007) (unpublished). Based on these facts,
    -12-
    the district court adopted the magistrate judge's recommendation that "the search
    warrant at issue . . . contains probable cause to support the search." Stults, 
    2007 WL 4284721
    , at *2.
    We affirm the district court's conclusion that the affidavit in support of the
    search warrant was supported by probable clause. The information contained in the
    affidavit shows that, through the P2P file-sharing program, Agent Cecchini was able
    to access and download files directly from Stults's computer that contained child
    pornography images. As a result, a fair probability existed that contraband would be
    found at Stults's residence in his personal computer. See 
    Palega, 556 F.3d at 714
    .3
    C. Mandatory Minimum
    Stults's third argument is that his prior conviction for attempted sexual assault
    on a child is insufficient to invoke the ten-year mandatory minimum sentence under
    18 U.S.C. § 2252(b)(2) because a conviction for attempted sexual assault on a child
    does not constitute "aggravated sexual abuse, sexual abuse, or abusive sexual conduct
    toward a minor or ward." According to Stults, had Congress intended a conviction for
    attempted sexual assault to trigger the increased penalty, it would have included such
    language in the statute. Furthermore, he asserts that his prior conviction is insufficient
    to invoke the mandatory minimum because it was based on a plea of nolo contendere.
    In response, the government argues that the district court properly concluded
    that the crime of attempted sexual assault on a child is an offense "relating to
    aggravated sexual abuse, sexual abuse, or abusive sexual conduct involving a minor,"
    thereby triggering the ten-year mandatory minimum. 18 U.S.C. § 2252(b)(2)
    (emphasis added).

    "[W]e need not address whether the Leon good-faith exception applies because
    the warrant was supported by probable cause." United States v. Abumayyaleh, 
    530 F.3d 641
    , 648 (8th Cir. 2008).
    -13-
    Section 2252(b)(2) of 18 U.S.C. provides:
    Whoever violates, or attempts or conspires to violate, paragraph (4) of
    subsection (a) shall be fined under this title or imprisoned not more than
    10 years, or both, but if such person has a prior conviction . . . under the
    laws of any State relating to aggravated sexual abuse, sexual abuse, or
    abusive sexual conduct involving a minor or ward, or the production,
    possession, receipt, mailing, sale, distribution, shipment, or
    transportation of child pornography, such person shall be fined under this
    title and imprisoned for not less than 10 years nor more than 20 years.
    (Emphasis added.) Thus, if a defendant has a prior conviction under state law
    "'relating to aggravated sexual abuse, sexual abuse, or abusive sexual conduct
    involving a minor or ward,' he is subject to a mandatory minimum sentence of ten
    years (and the maximum statutory sentence is increased from ten to twenty years)."
    United States v. McCutchen, 
    419 F.3d 1122
    , 1125 (10th Cir. 2005) (quoting 18 U.S.C.
    § 2252(b)(2)).
    "Unlike other sentencing enhancement provisions that specify a prior conviction
    must contain a certain element, § 2252(b)[(2)] contains no explicit reference to
    elements." United States v. Weis, 
    487 F.3d 1148
    , 1151 (8th Cir. 2007). Thus, the
    relevant "question is whether an offense is one 'relating to aggravated sexual abuse,
    sexual abuse, or abusive sexual conduct involving a minor,' not whether any specific
    element is present." 
    Id. at 1151–52.
    We apply a categorical approach "[t]o determine
    whether the prior offense qualifies as a predicate offense for the purpose of a sentence
    enhancement." United States v. Sonnenberg, 
    556 F.3d 667
    , 669–70 (8th Cir. 2009).
    "Under this approach, the sentencing court looks to the fact of conviction and the
    statutory definition of the prior offense and determines whether the full range of
    conduct encompassed by the state statute qualifies to enhance the sentence." 
    Id. at 670.
    -14-
    If the statute criminalizes both conduct that would qualify a defendant
    for an enhancement, as well as conduct that would not do so, the court
    may refer to the charging document, the terms of a plea agreement, the
    transcript of the colloquy, jury instructions, and other comparable
    judicial records to determine the basis for the guilty plea or verdict.
    
    Id. A prior
    conviction "relates to" aggravated sexual abuse, sexual abuse, or
    abusive sexual contact "whether or not the statute under which [the defendant] was
    convicted required actual harm." 
    Weis, 487 F.3d at 1152
    . "The phrase 'relating to'
    carries a 'broad' 'ordinary meaning,' i.e., ' 'to stand in some relation; to have bearing
    or concern; to pertain; refer; to bring into association with or connection with . . . .' '"
    
    Id. (quoting Morales
    v. Trans World Airlines, Inc., 
    504 U.S. 374
    , 383 (1992) (quoting
    Black's Law Dictionary 1158 (5th ed. 1979))) (holding that defendant's prior
    conviction for assault with intent to commit sexual abuse "related to" sexual abuse,
    as the prior conviction "required 'intent to commit sexual abuse'" and "[s]uch a mens
    rea demonstrate[d] the offense [was] one 'relating to' sexual abuse"). We have
    previously rejected a defendant's argument that "a state statute must criminalize only
    sexual acts involving physical touching to be 'relat[ed] to aggravated sexual abuse,
    sexual abuse, and abusive sexual conduct involving a minor or ward.'" 
    Sonnenberg, 556 F.3d at 670
    (quoting 18 U.S.C. § 2252(b)) (alteration in Sonnenberg). Instead, we
    have defined "sexual abuse of a minor" to mean "a perpetrator's physical or
    nonphysical misuse or maltreatment of a minor for a purpose associated with sexual
    gratification." 
    Id. at 671
    (internal quotations and citations omitted) (holding that
    defendant's prior conviction for committing lascivious acts with children "st[ood] in
    some relation to aggravated sexual abuse, sexual abuse, or abusive sexual conduct
    involving a minor or ward").
    The Fifth Circuit has held that a defendant's prior state conviction "for
    attempting to make a series of lewd or indecent proposals to engage in unlawful
    -15-
    sexual relations with a person he believed to be a fourteen-year-old girl" "related to"
    aggravated sexual abuse, sexual abuse, or abusive sexual conduct involving a minor,
    even though no actual minor and no actual sexual activity were involved. United
    States v. Hubbard, 
    480 F.3d 341
    , 343, 346–47 (5th Cir. 2007) (emphasis added).
    According to the court:
    Prior federal convictions for which the mandatory minimum sentence is
    imposed are not limited to offenses in which there was actual sexual
    contact between a defendant and the victim. We discern no intent on the
    part of Congress to impose such a limitation with regard to prior
    convictions under state law. Some of the non-contact conduct
    criminalized by the foregoing federal statutes would also constitute
    criminal conduct under many states' laws "relating to aggravated sexual
    abuse, sexual abuse, or abusive sexual conduct involving a minor."
    Additionally, § 2252A(b)(1) refers to prior convictions under state laws
    "relating to" abusive sexual conduct involving a minor, among other
    offenses. We must assume that Congress chose the words "relating to"
    for a purpose. As the Supreme Court said in another context in Morales
    v. Trans World Airlines, [
    504 U.S. 374
    , 383 (1992)], "The ordinary
    meaning of these words [relating to] is a broad one—'to stand in some
    relation; to have bearing or concern; to pertain; refer; to bring into
    association with or connection with,' Black's Law Dictionary 1158 (5th
    ed. 1979) . . . ."
    
    Id. at 347
    (emphasis added).
    Here, Stults pleaded nolo contendere to the charge of attempted sexual assault
    of a child in the second degree in Nebraska state court.4 Given the broad meaning of
    4
    Under § 28-320(1) of the Nebraska Revised Statutes, sexual assault in the
    second degree occurs when a person "subjects another person to sexual contact (a)
    without consent of the victim, or (b) who knew or should have known that the victim
    was physically or mentally incapable of resisting or appraising the nature of his or her
    -16-
    "relating to," and in light of the Fifth Circuit's persuasive holding in Hubbard with
    regard to prior convictions for attempt, we hold that Stults's conviction for attempted
    sexual assault of a child in the second degree clearly "stands in some relation to" or
    "pertains to" the crimes of aggravated sexual abuse, sexual abuse, or abusive sexual
    conduct involving a minor.
    Moreover, Stults's assertion that his prior conviction is insufficient to invoke
    the mandatory minimum because it was based on a plea of nolo contendere is without
    merit because Stults's plea "resulted in a finding of guilt." United States v. Storer, 
    413 F.3d 918
    , 922 (8th Cir. 2005) ("Because Congress provided no explicit language to
    the contrary in § 2252A(b)(2), we apply federal law to conclude that [the defendant's]
    Florida felony offense and nolo contendere plea, which resulted in a finding of guilt
    conduct." "Sexual assault" is "in the second degree . . . if the actor [causes] serious
    personal injury to the victim." 
    Id. § 28-320(2).
    Under § 28-320.01, "[a] person
    commits sexual assault of a child in the second or third degree if he or she subjects
    another person fourteen years of age or younger to sexual contact and the actor is at
    least nineteen years of age or older." In turn, "sexual contact" is defined as:
    the intentional touching of the victim's sexual or intimate parts or the
    intentional touching of the victim's clothing covering the immediate area
    of the victim's sexual or intimate parts. Sexual contact shall also mean
    the touching by the victim of the actor's sexual or intimate parts or the
    clothing covering the immediate area of the actor's sexual or intimate
    parts when such touching is intentionally caused by the actor. Sexual
    contact shall include only such conduct which can be reasonably
    construed as being for the purpose of sexual arousal or gratification of
    either party. Sexual contact shall also include the touching of a child
    with the actor's sexual or intimate parts on any part of the child's body
    for purposes of sexual assault of a child under sections 28-319.01 and
    28-320.01 . . . .

    -17-
    with adjudication withheld, qualifies as a conviction for purposes of § 2252A(b)(2)'s
    mandatory minimum ten-year sentence of imprisonment.").
    D. Distribution for Receipt of a Thing of Value
    According to Stults, the district court committed procedural error in applying
    the five-level enhancement under U.S.S.G. § 2G2.2(b)(3)(B) for distribution for the
    receipt, or expectation of receipt, of a thing of value, but not for pecuniary gain.
    Specifically, he asserts that insufficient evidence exists to show that he was aware that
    LimeWire would permit others to receive images from his computer.
    But the government contends that Stults's argument is without merit because the
    law of this circuit is that the enhancement automatically applies to a defendant who
    downloads and shares child pornography via a P2P file sharing network, as these
    networks exist for the purpose of users sharing files with one another. In the
    alternative, the government argues that even if the enhancement is not automatic, the
    district court took the additional step of finding that Stults was sufficiently computer
    savvy to know that he was allowing the distribution of child pornography.
    "On appeal, our first task is to ensure that the district court committed no
    significant procedural error, such as failing to calculate (or improperly calculating) the
    Guidelines range." United States v. Vickers, 
    528 F.3d 1116
    , 1120 (8th Cir. 2008)
    (internal quotations and citation omitted). "A non-harmless error in calculating the
    guidelines range requires a remand for resentencing." 
    Id. Section 2G2.2(b)(3)(B)
    provides for a five-level enhancement for "[d]istribution
    for the receipt, or expectation of receipt, of a thing of value, but not for pecuniary
    gain." "'Distribution for the receipt, or expectation of receipt, of a thing of value, but
    not for pecuniary gain' means any transaction, including bartering or other in-kind
    transaction, that is conducted for a thing of value, but not for profit." U.S.S.G. § 2G2.2
    n.1. "'Thing of value' means anything of valuable consideration. For example, in a
    -18-
    case involving the bartering of child pornographic material, the 'thing of value' is the
    child pornographic material received in exchange for other child pornographic
    material bartered in consideration for the material received." 
    Id. "'Distribution' means
    any act, including possession with intent to distribute, production, advertisement, and
    transportation, related to the transfer of material involving the sexual exploitation of
    a minor." 
    Id. Thus, "distribution
    includes posting material involving the sexual
    exploitation of a minor on a website for public viewing but does not include the mere
    solicitation of such material by a defendant." 
    Id. In United
    States v. Griffin, we held, as a matter of first impression, that a five-
    level enhancement for the distribution of child pornography for the receipt, or the
    expectation of receipt, of a thing of value, but not for pecuniary gain applied to a
    defendant who downloaded and shared child pornography files via an Internet P2P
    file-sharing network. 
    482 F.3d 1008
    , 1013 (8th Cir. 2007). In Griffin, police, pursuant
    to a search warrant, seized a computer from a residence. 
    Id. at 1010.
    Forensic analysis
    of the computer showed that a partially downloaded file containing child pornography
    had been downloaded to the computer from an IP address traced to the defendant. 
    Id. Local police
    executed a search warrant on the defendant's residence and seized a
    computer and several CD-ROMs containing approximately 67 video clips of child
    pornography. 
    Id. The defendant
    pleaded guilty to receiving and possessing child
    pornography, in violation of 18 U.S.C. §§ 2552(a)(2) and (a)(4)(B). 
    Id. The PSR
    concluded that the defendant was subject to a five-level enhancement
    pursuant to § 2G2.2(b)(2)(B) because the defendant's offense conduct involved the
    distribution of child pornography "'for the receipt, or expectation of receipt, of a thing
    of value, but not for pecuniary gain.'" 
    Id. (quoting §
    2G2.2(b)(2)(B)). The defendant
    objected to the enhancement, "denying that he distributed any child pornography and
    arguing that even if a distribution occurred, he did not distribute the images for the
    receipt, or the expectation of receipt, of a thing of value." 
    Id. Although the
    defendant
    admitted to downloading child pornography from Kazaa—an Internet P2P file-sharing
    -19-
    network—he argued that he only downloaded the images and videos for his personal
    use, not for distribution to others. 
    Id. But the
    defendant also admitted that he knew
    that Kazaa was a file-sharing program and knew that, by using it, other Kazaa users
    could also download files from his computer. 
    Id. According to
    the government, the
    defendant's use of Kazaa "with knowledge of its capabilities constituted distribution.
    By using the file-sharing site, [the defendant] enabled other Kazaa users to download
    files from [his] shared folder, including any child pornography files stored there." 
    Id. At an
    evidentiary hearing on the enhancement, the defendant admitted to being
    the primary user of the computer and that he had downloaded child pornography to
    his computer using Kazaa. 
    Id. An officer
    also testified that the defendant had admitted
    to knowing that by using Kazaa he would be able to download files from other Kazaa
    users and that other Kazaa users would be able to download files from him. 
    Id. But the
    officer did admit that when the defendant's computer was seized, the Kazaa program
    and the defendant's shared folder had been deleted from the computer, making the
    defendant unable to distribute images via Kazaa at that time. 
    Id. at 1010–11.
    The
    officer also testified that forensic analysis had recovered several deleted child
    pornography files on the computer and that the defendant's IP address was attached
    to the partially downloaded child pornography file. 
    Id. at 1011.
    This IP address
    established that the partially downloaded file had previously been on the defendant's
    computer, was available for distribution, and was distributed. 
    Id. On appeal,
    the issue before us was "whether an expectation of receipt of child
    pornography through Kazaa file sharing constitutes a 'thing of value, but not for
    pecuniary gain' for sentence enhancement purposes under § 2G2.2(b)(2)(B)." 
    Id. We noted
    that the defendant's "use of the peer-to-peer file-sharing network made the child
    pornography files in his shared folder available to be searched and downloaded by
    other Kazaa users as evidenced by the partially downloaded files recovered by Danish
    authorities." 
    Id. at 1012.
    As a result, we concluded that the defendant "was engaged
    in the distribution of child pornography." 
    Id. -20- We
    then addressed whether the defendant's "use of a file-sharing network to
    obtain child pornography from other network users, while allowing the child
    pornography files in his shared folder to be accessed and downloaded by others,
    constituted 'distribution for the receipt, or expectation of receipt, of a thing of value,
    but not for pecuniary gain' under § 2G2.2(b)(2)(B)." 
    Id. We held
    that, under the
    relevant facts, the government sufficiently proved that the defendant "expected to
    receive a thing of value—child pornography" by using Kazaa. 
    Id. at 1013.
    Recently, the Tenth Circuit declined to follow our holding in Griffin, based on
    its interpretation that Griffin mandates that "by sharing files on a file-sharing network,
    a defendant necessarily expects to receive a 'thing of value.'" United States v. Geiner,
    
    498 F.3d 1104
    , 1111 (10th Cir. 2007). Our holding in Griffin that "§ 2G2.2(b)(2)(B)'s
    five-level enhancement for the distribution of child pornography 'for the receipt, or the
    expectation of receipt, of a thing of value, but not for pecuniary gain' applies to a
    defendant who downloads and shares child pornography files via an internet
    peer-to-peer file-sharing network" was inseparable from our conclusion that "the
    government met its burden of establishing that [the defendant] expected to receive a
    thing of value—child pornography—when he used the file-sharing network to
    distribute and access child pornography files" by introducing the defendant's
    
    admissions. 482 F.3d at 1013
    . Specifically, the defendant in Griffin admitted that he
    "downloaded child pornography files from Kazaa, knew that Kazaa was a file-sharing
    network, and knew that, by using Kazaa, other Kazaa users could download files from
    him." 
    Id. Thus, whether
    a defendant qualifies for the five-level enhancement must be
    decided on a case-by-case basis, with the government bearing the burden of proving
    that the defendant "expected to receive a thing of value—child pornography—when
    he used the file-sharing network to distribute and access child pornography files." 
    Id. Here, there
    is no direct evidence that Stults expected to receive child
    pornography when he used LimeWire, as was the case in Griffin. But the government
    met its burden of proof through circumstantial evidence. The district court reasonably
    -21-
    deemed Stults, who is technically sophisticated in computer use, with knowing that
    he was distributing child pornography through his use of LimeWire. The district court
    cited the following facts in support of its determination that Stults's level of computer
    proficiency supported a finding that he knew how LimeWire worked: (1) Stults has
    a number of computers (two to three towers); (2) Stults had a large database; (3) Stults
    had saved substantial data obtained from other LimeWire users and kept it on CD-
    ROMs; (4) Stults's computer contained many images; and (5) a lot of data was in
    Stults's machine. In light of this circumstantial evidence, "we conclude there was
    sufficient evidence in the record to support the district court's ultimate finding and that
    it was not clearly erroneous." United State v. Cordy, 
    560 F.3d 808
    , 817 (8th Cir.
    2009).
    E. Reasonableness of Sentence
    Stults maintains that even if this court finds that the district court's sentence is
    not procedurally flawed, it remains a substantively unreasonable sentence because it
    is greater than necessary to promote the goals of 18 U.S.C. § 3553(a).
    In response, the government points out that the district court sentenced Stults
    well below the advisory Guidelines range of 188 to 235 months to 144 months'
    imprisonment.
    "Absent reversible procedural error, we . . . review the reasonableness of the
    court's sentence for abuse of discretion." 
    Vickers, 528 F.3d at 1120
    . Where the district
    court in imposing a sentence makes "an individualized assessment based on the facts
    presented," addressing the defendant's proffered information in its consideration of the
    § 3553(a) factors, such sentence is not unreasonable. Gall v. United States, 
    128 S. Ct. 586
    , 597 (2007) (in reviewing sentence for abuse of discretion, appeals court must
    first ensure there was no significant procedural error, and then assess substantive
    reasonableness of sentence); see also United States v. Haack, 
    403 F.3d 997
    , 1004 (8th
    Cir.2005) (listing circumstances that may warrant finding of abuse of discretion).
    -22-
    Here, the district court issued a sentencing memorandum in which it thoroughly
    discussed all of the § 3553(a) factors. Furthermore, at the sentencing hearing, the
    district court adequately explained why it was sentencing Stults below the applicable
    Guidelines range of 188 to 235 months. Accordingly, we hold that a sentence of 144
    months' imprisonment is not substantively unreasonable.
    F. Special Conditions of Supervised Release
    Stults's final argument is that four of the special conditions that the district court
    imposed constitute a deprivation of liberty more burdensome than necessary to serve
    federal sentencing goals. Specifically, Stults objects to special conditions 4, 5, 7, and
    12, which prohibit him from (1) having contact or residing with children under the age
    of 18, including his own children, unless approved in advance and in writing by the
    probation officer in consultation with the treatment providers; (2) accessing or coming
    within 500 feet of schools, school yards, parks, arcades, playgrounds, amusement
    parks, or other places used primarily by children under the age of 18 unless approved
    in advance and in writing by the probation officer; (3) accessing, viewing, or
    possessing any pornographic sexually-oriented or sexually-stimulating materials,
    including visual, auditory, telephonic, or electronic media, computer programs or
    services and patronizing any place where such material or entertainment is available
    without the express permission of the United States Probation Office; and (4) except
    for purposes of his employment, using or having access to any electronic media that
    has Internet service or photography capability without the express permission from
    the United States Probation Office.
    In response, the government asserts that the district court did not abuse its
    discretion in imposing the aforementioned special conditions because restricting Stults
    from contact with children and limiting his access to the Internet are reasonable
    measures to protect society, in light of Stults's sex-related felony convictions.
    -23-
    "It is fundamental that a district judge has wide discretion in formulating the
    terms of supervised release." United States v. Levering, 
    441 F.3d 566
    , 569 (8th Cir.
    2006) (internal quotations and citation omitted). But such discretion "is limited by the
    requirement that the conditions be reasonably related to § 3553(a) factors, involve no
    greater deprivation of liberty than is reasonably necessary, and are consistent with any
    pertinent policy statements issued by the United States Sentencing Commission." 
    Id. (internal quotations
    and citation omitted). "We review the district court's imposition
    of special conditions of supervised release for abuse of discretion." 
    Id. Applying this
    standard of review, we will consider each one of Stults's objections in turn.
    1. Special Condition 4
    Special condition 4 provides that Stults "shall have no contact, nor reside with
    children under the age of 18, including his own children, unless approved in advance
    and in writing by the probation officer in consultation with the treatment providers."
    If Stults has "incidental contact with children," he must report such contact "to the
    probation officer and the treatment provider."
    Stults argues that this condition "prohibits a host of benign and commonplace
    contact." According to Stults, "[s]uch a broad prohibition is unnecessary given the
    restrictions that are already imposed upon Stults as a convicted sex offender."
    In response, the government points out that special condition 4 permits Stults
    to have contact with children under the age of 18 if he secures the approval of his
    probation officer. According to the government, "[c]hildren are members of the public
    that the terms of supervised release seeks to protect," and, given Stults's criminal past,
    such condition "is reasonably necessary to protect the public and is not overly
    restrictive."
    We have previously upheld special conditions substantially similar to special
    condition 4 with regard to defendants who have pleaded guilty to possessing or
    -24-
    receiving child pornography. See, e.g., United States v. Mickelson, 
    433 F.3d 1050
    ,
    1057 (8th Cir. 2006) (upholding as reasonable a special condition preventing the
    defendant, who pleaded guilty to receiving child pornography, from having contact
    with anyone under the age of 18 without the express written permission of the
    probation officer); United States v. Mark, 
    425 F.3d 505
    , 507–08 (8th Cir. 2005)
    (upholding as reasonable special condition prohibiting the defendant, who was
    convicted of possessing child pornography, from having any contact with, or residing
    with, any children under 18 years of age, including his own children, unless the
    probation officer gave prior approval in writing); United States v. Crume, 
    422 F.3d 728
    , 733–34 (8th Cir. 2005) (rejecting the argument of defendant, who was convicted
    of knowingly receiving child pornography, that the special condition prohibiting him
    from "contact with children under the age of eighteen without the written consent of
    his probation officer" was an "unnecessary deprivation of his liberty interest in having
    contact with his own children" because the condition did not completely bar him from
    interacting with his children); United States v. Vick, 
    421 F.3d 794
    , 795 (8th Cir. 2005)
    (upholding a supervised release condition that prohibited the defendant, who was
    convicted of possessing child pornography, from having any contact with children
    under the age of 18, including his daughter, unless he received prior written approval
    from his probation officer because the condition was tailored to the defendant's
    "extensive history with minors, was reasonably related to the nature of seriousness of
    his offense, and was needed to deter [the defendant] and protect the public").
    Therefore, in light of this court's precedent, we hold that the district court did
    not abuse its discretion in imposing special condition 4.5
    5
    "In the case of an association restriction, [we note that] the Third Circuit
    determined the district court's delegation of 'absolute authority to the Probation Office
    to allow any such contacts while providing no guidance whatsoever for the exercise
    of that discretion' was untenable." United States v. Rodriguez, 
    558 F.3d 408
    , 416 (5th
    Cir. 2009) (quoting United States v. Voelker, 
    489 F.3d 139
    , 154 (3d Cir. 2007)). In
    Voelker, the Third Circuit concluded that "[b]ecause the defendant had been sentenced
    -25-
    2. Special Condition 5
    Special condition 5 provides that Stults "shall not access or come within 500
    feet of schools, school yards, parks, arcades, playgrounds, amusement parks, or other
    places used primarily by children under the age of 18 unless approved in advance and
    in writing by the probation officer."
    Stults objects to this special condition, asserting that it "not only prohibits him
    from residing within 500 feet of a school or child[c]are center" but also" prohibits him
    from coming within 500 feet of any place used primarily by children at any time for
    any reason." According to Stults, such a condition is a far greater deprivation of
    liberty than is reasonably necessary to fulfill the federal sentencing goals.
    In response, the government notes that the district court included the qualifier
    "except when approved in advance and in writing by the Probation Office" to the
    special condition. And, it also cites the district court's response to Stults's objection
    to the special condition, in which the district court stated:
    If he drives to work every day and he goes down Dodge Street every
    day, which is a main thoroughfare, and that's within 500 feet of a school,
    or park, which it may be, then he can get permission to drive to and from
    work, but otherwise I would suggest that he change his route.
    to a lifetime of supervised release," "designating the probation officer the sole
    authority for deciding if the defendant could ever have unsupervised contact with any
    minor, including his own children, was an impermissible 'unbridled delegation of
    authority.'" 
    Id. (quoting Voelker,
    489 F.3d at 154). Here, Stults never objected to any
    of the special conditions on the grounds that they were imposed for a lifetime;
    accordingly, we need not address the effect of the district court sentencing Stults to
    a lifetime of supervised release.
    -26-
    In light of the district court's comments, the government concludes that the condition
    "does not prohibit Stults from living, working, or driving to such places as he may do
    so if he secures the approval of the Probation Officer."
    This court has not previously addressed the exact condition at issue here, but
    we have addressed similar conditions. First, in United States v. JoDon, the defendant,
    who pleaded guilty to transportation of obscene matter, challenged "the district court's
    imposition of special conditions of supervised release barring [the defendant] from
    engaging in activities providing access to children, loitering near certain areas
    frequented by children, or having a post office or private mail box, without his
    probation officer's earlier approval." 19 Fed. Appx. 443, 444 (8th Cir. 2001)
    (unpublished per curiam). Rejecting the defendant's challenge, we held that "the
    challenged conditions are reasonably related to his crime and his rehabilitation, they
    are intended to protect the public from this convicted sexual offender, and they
    involve no greater restraint of liberty than reasonably necessary to accomplish their
    purposes." 
    Id. Second, in
    United States v. Ristine, the defendant, who pleaded guilty to
    receiving child pornography, challenged a special condition barring him "from places
    where minor children under the age of 18 congregate, such as residences, parks,
    beaches, pools, daycare centers, playgrounds, and schools without the prior written
    consent of the probation officer," arguing that such condition "is vague and could be
    read to ban him from all parks, beaches, and pools; if read in this manner, the
    restriction would be overbroad." 
    335 F.3d 692
    , 696 (8th Cir. 2003) (internal
    quotations omitted). We upheld the condition, finding that its purpose was "to limit
    [the defendant's] access to children. It is therefore sensible for the condition to restrict
    [the defendant's] presence at places where children are actually present." 
    Id. Third, in
    United States v. Kerr, the district court imposed a condition of
    supervised release that required the defendant, who was convicted of possession and
    -27-
    distribution of child pornography, "to obtain permission from the probation office
    prior to contacting minors or going to places where minors congregate." 
    472 F.3d 517
    ,
    520 (8th Cir. 2006). In upholding this condition, we observed that "[t]he undisputed
    evidence demonstrates [that the defendant] possessed and distributed child
    pornography, some depicting the sadistic and violent sexual abuse of pre-teen
    minors." 
    Id. at 522.
    We noted that "[t]his court has, in several instances, upheld
    similar conditions limiting contact with minors in child pornography possession cases,
    albeit in cases involving defendants with records of sexual abuse of minors." 
    Id. (citing Mark,
    425 F.3d at 508; 
    Crume, 422 F.3d at 734
    ; United States v. Heidebur, 
    417 F.3d 1002
    , 1004 (8th Cir. 2005)). We found that "the absence of such a history [of
    sexually abusing minors] is not necessarily determinative when deciding whether the
    district court erred in imposing contact conditions." 
    Id. at 523
    (citing 
    Mickelson, 433 F.3d at 1051
    ). As a result, we held that although the defendant had no history of
    abusing minors, "his offenses include both the possession and distribution of child
    pornography" and that such "offenses are more serious than mere possession
    offenses." 
    Id. We pointed
    out that the defendant admitted to "distributing child
    pornography and also admits he possessed pornography depicting children under
    twelve and sadomasochistic violence." 
    Id. Additionally, we
    found it relevant that the
    condition did not prohibit the defendant from contacting minors or entering places
    where minors congregate "so long as he obtains prior permission from the probation
    office. Furthermore, because [the defendant was] childless, he [was] not restricted
    from contacting his own children." 
    Id. Therefore, we
    held that "these contact
    conditions are not unreasonably restrictive given the circumstances . . . ." 
    Id. In the
    present case, we hold that special condition 5 is not an impermissible
    deprivation of Stults's liberty. First, we have upheld special conditions (1) prohibiting
    a defendant from "loitering" near areas frequented by children, JoDon, 19 Fed. Appx.
    at 444, and (2) barring the defendant from places where children "congregate,"
    including "residences, parks, beaches, pools, daycare centers, playgrounds, and
    schools," 
    Ristine, 335 F.3d at 696
    . Similarly, Stults is prohibited from coming within
    -28-
    500 feet of "schools, school yards, parks, arcades, playgrounds, amusement parks, or
    other places used primarily by children."
    Second, like the defendant in Kerr who was prohibited from "going to places
    where minors 
    congregate," 472 F.3d at 520
    , the evidence shows that Stults possessed
    child pornography, "some depicting the sadistic and violent sexual abuse of pre-teen
    minors." 
    Kerr, 472 F.3d at 522
    . Furthermore, unlike the defendant in Kerr, Stults does
    have a history of sexually abusing minors, as he was previously convicted of
    attempted sexual assault of a child. The PSR recounts that this conviction involved
    Stults's 11-year-old niece and that, according to the niece, Stults did, in fact, sexually
    abuse her.
    Third, as in Kerr, special condition 5 is not a complete prohibition on Stults
    coming within 500 feet of places used primarily by children; instead, it provides that
    Stults may come within 500 feet of such places if "approved in advance and in writing
    by the probation officer." Conditions requiring the prior approval of a probation
    officer are "consistently upheld." 
    Rodriguez, 558 F.3d at 415
    (holding that, in
    imposing supervised release conditions prohibiting defendant from associating with
    any minor child except in the presence and supervision of a specifically designated
    adult and prohibiting defendant from residing near schools, youth centers, and other
    enumerated institutions without prior approval, district court permissibly delegated
    to defendant's probation officer duties of designating supervising adult and of
    approving defendant's residence within restricted areas). We also note that Stults has
    not alleged that the district court "abdicated its judicial responsibility" in requiring the
    probation officer's prior approval. See 
    id. Finally, Stults
    asserts that special condition 5 is unreasonable because it
    prevents him from even coming within, as opposed to merely residing within, 500 feet
    of places primarily used by children. This condition is not unreasonable in light of
    Stults's individual characteristics as an offender. Stults has a history of sexually
    -29-
    abusing minors, as he was previously convicted of attempted sexual assault of a child.
    Additionally, the condition is not a blanket prohibition, as Stults may seek written
    advance permission from his probation officer. The probation officer may then
    exercise his discretion to allow Stults to come within 500 feet of the prohibited areas.
    3. Special Condition 7
    Special condition 7 prohibits Stults from "access[ing], view[ing] or possess[ing]
    any pornographic sexually oriented or sexually stimulating materials, including visual,
    auditory, telephonic, or electronic media, computer programs or services" and from
    "patroniz[ing] any place where such material or entertainment is available without the
    express permission of the United States Probation Office."
    On appeal, Stults argues that special condition 7 is too vague because the term
    "pornography" is "entirely subjective" and "lacks any recognized legal definition."
    In response, the government relies on United States v. Boston, 
    494 F.3d 660
    (8th Cir. 2007), in which this court upheld a special condition of supervised release
    prohibiting the defendant from viewing, possessing, or entering a location that sold
    any form of pornography or sexually explicit material deemed inappropriate by his
    probation officer or treatment staff.
    As a threshold matter, we note that, at the sentencing hearing, Stults objected
    to special condition 7 not on the basis of vagueness but instead on the ground that the
    condition violated the First Amendment because it was overbroad, as it prohibited him
    from accessing lawful materials. Specifically, Stults's counsel stated, "[I]t seems to me
    if it's lawful material, then he would have a 1st Amendment right and another right to
    possess those types of materials." Our review of the sentencing transcript reflects that
    counsel never objected to the condition based on vagueness; therefore, we must
    review Stults's argument that the condition is unconstitutionally vague for plain error.
    -30-
    See 
    Ristine, 335 F.3d at 694
    ("When a defendant failed to raise a timely objection to
    those terms, however, our review is only for plain error.").
    In Ristine, the defendant "challenge[d] [for the first time on appeal] a special
    condition of supervision that prohibit[ed] him from owning or possessing any
    pornographic materials," from using "any form of pornography or erotica," and from
    entering "into any establishment where pornography or erotica can be obtained or
    viewed." 
    Id. (internal quotations
    omitted). The defendant argued that such restrictions
    were "overbroad and vague." 
    Id. According to
    the defendant, the restrictions were
    overbroad because they "prevent[ed] him from accessing materials that he believe[d]
    he ha[d] a First Amendment right to view." 
    Id. Additionally, he
    argued that the
    restrictions were vague because "they fail[ed] to give him adequate notice as to when
    he would violate the condition." 
    Id. Applying plain
    error review, we rejected the
    defendant's argument. 
    Id. First, we
    held that the defendant's "argument that the
    pornography-related restrictions [were] overbroad [was] without merit," as the record
    "demonstrate[d] [the defendant's] obsession with or addiction to child pornography."
    
    Id. Second, we
    recognized the defendant's "more powerful argument . . . that the
    vagueness of 'pornography' leaves him without notice as to what film, prose, and art
    he may view without violating the challenged condition" and noted a circuit split as
    to whether such conditions are unconstitutionally vague. 
    Id. at 695
    (citing United
    States v. Loy, 
    237 F.3d 251
    , 261, 266 (3d Cir. 2001) (striking down a condition
    banning a defendant from possessing "all forms of pornography, including legal adult
    pornography" because "without a more definitive standard to guide the probation
    officer's discretion, there is a real danger that the prohibition on pornography may
    ultimately translate to a prohibition on whatever the officer personally finds
    titillating"); United States v. Phipps, 
    319 F.3d 177
    , 192–93 (5th Cir. 2003) (upholding
    a condition that prohibited the defendants from possessing "sexually oriented or
    sexually stimulating materials")). But we upheld the condition, concluding that
    because "the current law concerning this issue is unsettled," the district court did not
    commit plain error in imposing the condition. 
    Id. at 695
    .
    -31-
    Ristine is factually analogous and controls the result in this case, as Stults raised
    the vagueness argument for the first time on appeal. Therefore, we hold that the
    district court did not plainly err in imposing a ban on pornographic material as a
    condition of supervised release.
    4. Special Condition 12
    Special condition 12 provides that, "[e]xcept for purposes of his employment,
    the defendant is prohibited from using or having access to any electronic media that
    has internet service or photography capability without express permission from United
    States Probation Office."6
    According to Stults, this condition "is far more restrictive than reasonably
    necessary to effectuate federal sentencing goals" because he merely possessed child
    pornography and no evidence exists that he used his computer to do anything more
    than merely possess such pornography.
    In response, the government notes that Stults is not completely banned from
    accessing the Internet, as he can obtain the express permission of his probation officer;
    in addition, he can access the Internet for purposes of his employment. Also, the
    government maintains that although Stults was convicted for mere possession of child
    pornography, he (1) was subject to a ten-year mandatory minimum sentence based
    upon a prior conviction related to the sexual abuse of minors; (2) obtained child
    pornography and shared it through LimeWire, a P2P file-sharing network; and (3)
    possessed child pornography depicting bondage and penetration of adolescent girls.
    "The widespread use of computers and the internet have provided new
    opportunities to deal in and view child pornography, and courts have fashioned some
    6
    Special condition 12 also provides that Stults "will sign any and all releases of
    information as it relates to cell phone carriers." Stults did not object to this portion of
    the condition before the district court and likewise has not challenged it on appeal.
    -32-
    special conditions of release for defendants convicted of such crimes to place
    restrictions on their use of computers and the internet." United States v. Fields, 
    324 F.3d 1025
    , 1027 (8th Cir. 2003). "In cases where defendants used computers or the
    internet to commit crimes involving greater exploitation, such restrictions have been
    upheld." 
    Id. But "[a]ppellate
    courts have overturned conditions seen as overly
    restrictive, especially in cases involving simple possession of child pornography." 
    Id. (upholding, under
    plain error review, special condition of supervised release
    prohibiting defendant, who was convicted of selling child pornography, from owning
    or operating any photographic equipment, including computers, scanners and printers;
    prohibiting defendant from having internet service in his residence; and barring
    defendant's possession of a computer unless permission was granted by probation
    officer because "[s]elling subscriptions to child pornography is more serious than a
    possessory offense" and "the conditions d[id] not constitute a total ban on his use of
    computers or the internet").
    This court, on several occasions, has addressed special conditions of release
    similar to special condition 5. In Ristine, the defendant, who pleaded guilty to
    receiving child pornography, challenged special conditions that "prohibited [him]
    from owning or operating any photographic equipment, including, but not limited to,
    cameras, digital cameras, videotaping recorders, camcorders, computers, scanners, and
    printers" and "permit[ted] [the defendant] to possess a computer" as long as the
    defendant "consent[ed] to periodic unannounced examinations and inspections of his
    computer as well as to the installation of hardware or software that monitors his
    computer 
    use." 335 F.3d at 695
    (internal quotations omitted). "Even if [the defendant]
    [was] permitted to have a computer, he [was prohibited from having] Internet service
    at his residence." 
    Id. In Ristine,
    we addressed two considerations in determining whether imposition
    of the conditions was an abuse of discretion. First, we considered whether evidence
    existed "that the defendant did more than merely possess child pornography." 
    Id. at -33-
    696. Second, we considered whether the defendant was "completely prohibited from
    using a computer." 
    Id. Applying these
    considerations, we found that (1) the defendant
    "more than merely possessed images of child pornography—he exchanged the images
    with other Internet users, and he attempted to arrange sexual relations with underage
    girls" and (2) the defendant was not "wholly barred from using a computer." 
    Id. In contrast,
    we held in United States v. Crume that a condition of supervised
    release for knowingly receiving child pornography and knowingly possessing child
    pornography, which completely barred the defendant's access to computers and the
    Internet without first receiving written consent from his probation officer, was a
    greater deprivation of the defendant's rights than was reasonably necessary. 
    422 F.3d 728
    , 732–33 (8th Cir. 2005). In so holding, we distinguished Fields and Ristine,
    explaining:
    Although [the defendant] has a lengthy history of grievous sexual
    misconduct, the record is devoid of evidence that he has ever used his
    computer for anything beyond simply possessing child pornography. We
    are not convinced that a broad ban from such an important medium of
    communication, commerce, and information-gathering is necessary
    given the absence of evidence demonstrating more serious abuses of
    computers or the Internet. We are confident that the district court can
    impose a more narrowly-tailored restriction on [the defendant's]
    computer use through a prohibition on accessing certain categories of
    websites and Internet content and can sufficiently ensure his compliance
    with this condition through some combination of random searches and
    software that filters objectionable material.
    
    Id. at 733
    (emphasis added).
    Although it is a close call, we think that this case is more like Ristine than
    Crume and hold that the special condition barring Internet access unless approved by
    the probation office is sufficiently tailored to the particular facts of this case. The same
    -34-
    facts and considerations that justify imposition of the five-level enhancement also
    support the district court's imposition of this condition of supervised release. The
    condition is not a blanket prohibition against all computer use. Stults will have
    unlimited access to computers for employment purposes. Plus, Stults may obtain
    permission from his probation officer and gain computer access for any and all other
    legitimate personal purposes.
    III. Conclusion
    Accordingly, we affirm the judgment of the district court.
