    Before KELLY, BALDOCK, and EBEL, Circuit Judges.
    KELLY, Circuit Judge.
    Defendant-Appellant Michael Loren Dunn was convicted of possession of
    child pornography, 18 U.S.C. § 2252A(a)(5)(B) (Count I), receipt of child
    pornography, 18 U.S.C. § 2252A(a)(2) & (b) (Count II), and distribution of child
    pornography, 18 U.S.C. § 2252A(a)(2) & (b) (Count III). 
    1 Rawle 583
    –85. The
    district court sentenced Mr. Dunn to 144 months’ imprisonment and a 25-year
    term of supervised release. 
    Id. at 1042–44.
    The district court imposed several
    special conditions of supervised release, some of which restrict Mr. Dunn’s
    ability to use and access both computers and the Internet. In addition to his
    sentence, Mr. Dunn was ordered to pay $583,955 in restitution to one of the
    victims depicted in images he possessed and distributed. 
    Id. at 1046.
    On appeal, Mr. Dunn argues that: (1) an erroneous jury instruction relieved
    the government of its burden to prove that he “distributed” child pornography; (2)
    his convictions for receipt and possession of child pornography are multiplicitous
    and thus violate the Double Jeopardy Clause; (3) the special condition of
    supervised release requiring him to comply with a computer and Internet
    monitoring program was not supported by necessary findings of fact; and (4) the
    district court applied the wrong legal standard in determining the amount of
    restitution owed by Mr. Dunn. Exercising jurisdiction pursuant to 28 U.S.C.
    § 1291 and 18 U.S.C. § 3742(a), we affirm in part, reverse in part, and remand for
    further proceedings consistent with this opinion.
    Background
    This case involves the downloading and sharing of child pornography on an
    -2-
    Internet-based peer-to-peer network. Like many peer-to-peer file-sharing
    programs, LimeWire permits users to search for and download electronic files
    from other users who are running the program. Generally speaking, these file-
    sharing programs are effective only if users make their own files available for
    sharing with other users of the same program. For this reason, LimeWire’s
    default setting automatically places a user’s downloaded files into a shared folder;
    the contents of the shared folder are, by default, searchable by other users and the
    files contained therein may be downloaded at the other users’ command.
    Relevant to this case, this default setting can be changed manually so that a user’s
    downloaded files are not automatically made available to other LimeWire users.
    The Utah Internet Crimes Against Children Task Force monitors peer-to-
    peer networks using an automated search program that identifies probable child
    pornography files. Law enforcement can often identify these files by their SHA-1
    (secured hash algorithm) values. Similar to human DNA, SHA-1 values are
    unique, 32-character identifiers given to a file by a universal algorithm. Separate
    files with the same SHA-1 values will have identical content.
    Between 2007 and 2009, the Utah Task Force observed a particular
    internet-protocol (IP) address offering to share files on LimeWire with SHA-1
    values consistent with known child pornography files. Law enforcement agents
    were able to trace the IP address to Mr. Dunn. Subsequently, a warrant was
    obtained authorizing the search and seizure of Mr. Dunn’s computers. The
    -3-
    warrant was executed on March 26, 2009 and resulted in the seizure of four
    computers and one external hard drive.
    A forensic analysis of the computers revealed that at least 20 child
    pornography images had been downloaded via LimeWire. All of the files were
    stored in the program’s shared folder and were therefore available for download
    to other users. At trial, both sides presented expert witnesses. Mr. Dunn
    presented an expert witness to rebut the government’s computer forensics expert.
    At the close of evidence, each side submitted proposed jury instructions. Mr.
    Dunn’s proposed instruction on the distribution offense would have required the
    jury to find, as an element of the offense, that a third-party had actually received
    child pornography from Mr. Dunn. The district judge rejected this instruction,
    and instead instructed the jury that “if a person knowingly makes images
    available on a peer-to-peer file sharing network, such as LimeWire, this is
    considered ‘distribution’ of the 
    images.” 1 Rawle at 850
    . The jury found Mr. Dunn
    guilty on all three counts.
    Based upon a total offense level of 37 and a criminal history category of I,
    the Presentence Report calculated the sentencing range of imprisonment as 210-
    262 
    months. 2 Rawle at 72
    . However, despite denying Mr. Dunn’s request for a
    downward adjustment based on acceptance of responsibility and a request for a
    five-year minimum sentence, the district court imposed a below-Guidelines
    sentence of 144 months’ imprisonment. Further, the district court imposed a 25-
    -4-
    year term of supervised release and several special conditions of supervised
    release. One of the special conditions requires Mr. Dunn to participate in the
    Computer and Internet Monitoring Program conducted by Probation and Pretrial
    Services. This program restricts Mr. Dunn’s ability to use and access computers
    and the Internet, and requires Mr. Dunn to obtain pre-approval from his probation
    officer prior to engaging in certain computer-related activities. Mr. Dunn was
    previously employed as both a computer technician and computer teacher.
    A restitution request was filed by a representative (Professor Paul Cassell,
    through the University of Utah Appellate Law Clinic) of one of the victims
    depicted in the child pornography images possessed and distributed by Mr. Dunn.
    The victim, “Vicky,” sought restitution under 18 U.S.C. § 2259 in the full amount
    of her unpaid aggregate losses—$583,955. Mr. Dunn requested that Vicky’s
    representative produce an up-to-date economic report establishing the amount of
    Vicky’s losses and a causal link between Mr. Dunn’s conduct and those losses.
    The district court denied that request, found that Vicky was a victim of Mr.
    Dunn’s crimes and, most importantly, “conclude[d] that all her losses were
    proximately caused by Dunn.” 1 R. Supp. at 32. As such, the court ordered Mr.
    Dunn to pay Vicky restitution in the full amount of her unpaid aggregate losses.
    
    Id. at 37.

    Discussion
    Mr. Dunn raises four issues on appeal. First, he argues that the district
    court erred by instructing the jury that it could convict him on the distribution
    charge simply by finding that he made child pornography available for sharing on
    LimeWire. Second, he argues that under United States v. Benoit, 
    713 F.3d 1
    (10th Cir. 2013), his sentences for receipt and possession of child pornography
    are multiplicitous and violate the Double Jeopardy Clause. Third, he contends
    that the district court did not make the necessary findings to support the
    imposition of a special condition of supervised release concerning his ability to
    use and access computers and the Internet. Fourth, he argues that the district
    court applied the wrong legal standard when it determined that he owed a victim
    the full amount of her unpaid aggregate losses.
    The government agrees that the district court erred regarding the second
    and fourth issues; however, it contends that the district court’s findings of fact on
    the restitution issue should be left undisturbed. We consider each of these
    arguments in turn.
    A.    Jury Instructions Regarding “Distribution”
    We first consider Mr. Dunn’s challenge to the jury instructions on the
    distribution charge. Our review of jury instructions is de novo, United States v.
    Serrata, 
    425 F.3d 886
    , 898 (10th Cir. 2005), and we will “reverse for instructional
    error only where it is prejudicial in view of the entire record.” United States v.
    -6-
    Wittgenstein, 
    163 F.3d 1164
    , 1169 (10th Cir. 1998); see United States v. Batton,
    
    602 F.3d 1191
    , 1199 (10th Cir. 2010).
    Mr. Dunn contends that the jury instructions on the distribution charge
    amounted to a “mandatory” presumption in favor of conviction. It seems to us,
    however, that Mr. Dunn is actually making two arguments. First, instead of
    permitting the jury to infer distribution based on Mr. Dunn’s act of placing files
    into a folder available for sharing, the jury instructions required the jury to find
    that this act was, under the law, distribution itself. Second, the instructions
    “required the jury to disregard his expert testimony and with it much of his theory
    of the case.” Aplt. Rep. Br. at 1. The government counters that the instruction
    was a correct statement of the law and any error was harmless because the jury’s
    verdict necessarily encompassed attempted distribution.
    The two instructions at issue here are Instructions 47 and 48. The former
    lists the essential elements of the distribution offense and instructs the jury that it
    must find beyond a reasonable doubt that Mr. Dunn:
    Did knowingly distribute or knowingly attempt to distribute child
    pornography, to-wit: knowingly made available for sharing
    electronically image files that he knew depicted children engaged in
    sexually explicit 
    conduct. 1 Rawle at 849
    . The latter provides:
    [I]f a person knowingly makes images available on a peer-to-peer file
    sharing network, such as LimeWire, this is considered “distribution”
    of the images. In other words, the Government may meet its burden
    of proof on this element by showing that Defendant knowingly
    -7-
    allowed others access to his LimeWire shared folder.
    
    Id. at 850
    (emphasis added). In Mr. Dunn’s view, these instructions were
    impermissible because they “requir[ed] the jury to infer the conclusion that Mr.
    Dunn had distributed child pornography if the government proved the predicate
    fact he knowingly allowed child pornography to be accessible in the shared
    folders of his LimeWire account.” Aplt. Br. at 15.
    As an initial matter, the requirement that Mr. Dunn knowingly allowed the
    contraband to be accessible cuts against his theory of a mandatory presumption of
    distribution. More importantly, however, in United States v. Shaffer, 
    472 F.3d 1219
    , 1223–24 (10th Cir. 2007), we concluded that active distribution or transfer
    of possession to another is not required to prove distribution under § 2252A(a)(2):
    a reasonable jury could find that knowingly allowing others access to child
    pornography over the internet is sufficient. Thus, the defendant’s placement of
    child pornography files into a shared folder accessible to other users was itself
    sufficient for the trier of fact to conclude that the defendant had “distributed” the
    material. 
    Id. at 1224.
    We analogized the defendant’s conduct to that of an
    operator of a self-serve gas station and reasoned that “[h]e may not have actively
    pushed pornography on [peer-to-peer] users, but he freely allowed them access to
    his computerized stash of images and videos and openly invited them to take, or
    download, those items.” 
    Id. at 1223.
    Shaffer controls this case. Moreover, in an
    unpublished order and judgment, we recently rejected a similar challenge to an
    -8-
    identical instruction. United States v. Dayton, 485 F. App’x 937, 941 (10th Cir.
    2012).
    Mr. Dunn’s second argument is that “the instructions required the jury to
    accept the government’s evidence about how LimeWire operates.” Aplt. Rep. Br.
    at 1. He similarly contends that the same instructions prohibited the jury from
    believing any of the defense expert’s testimony. 
    Id. This argument
    completely misses the mark. Mr. Dunn points to nothing,
    and we have found nothing, in the instructions that requires the jury to accept the
    government’s evidence. There is nothing in the instructions that even remotely
    suggests that the jury must, or even should, reject the defense expert’s testimony
    and theory of the case. To the contrary, the jurors were instructed that they were
    to weigh all of the evidence in the case, that they were the sole judges of the
    credibility of the witnesses, and that they alone determined the weight that such
    testimony deserved. 
    1 Rawle 806
    , 807, 812–813. All of the issues Mr. Dunn raises
    on this point go to the weight, credibility, and sufficiency of the evidence, rather
    than some error in the jury instructions that relieved the government of its burden
    of proof. Mr. Dunn overlooks the most reasonable (and probable) explanation for
    the jury’s conclusions—that the jury rejected the defense theory of the case and
    found the government’s evidence sufficient and reliable. Accordingly, we
    conclude that the instructions were proper.
    -9-
    B.    Multiplicitous Sentences for Possession and Receipt of Child Pornography
    Next, Mr. Dunn argues that his sentences for possession and receipt of
    child pornography violate the Double Jeopardy Clause because they are
    multiplicitous. Mr. Dunn did not raise this argument in the district court and
    therefore we review only for plain error. United States v. Frierson, 
    698 F.3d 1267
    , 1269 (10th Cir. 2012). To succeed under plain error review, the defendant
    must show (1) an error, (2) that is plain, (3) which affects substantial rights, and
    (4) seriously affects the fairness, integrity, or public reputation of judicial
    proceedings. United States v. Gonzalez-Huerta, 
    403 F.3d 727
    , 732 (10th Cir.
    2005) (en banc).
    Both parties agree that it is plain error to punish Mr. Dunn on both the
    receipt and possession charges. At the time Mr. Dunn was sentenced, this court
    had already decided United States v. Benoit, 
    713 F.3d 1
    (10th Cir. 2013), where
    we held that “possession is a lesser included offense of receipt in cases in which
    the same child pornography forms the basis of each charge.” 
    Id. at 6–7.
    In that
    case, the defendant’s possession and receipt convictions were predicated on the
    same child pornography images. Thus, we found that the multiplicity doctrine
    was implicated because the two charges were based on the same conduct, rather
    than “two distinct sets of conduct.” 
    Id. at 16
    (internal quotations omitted). We
    reversed and remanded with instructions to vacate one of the convictions. 
    Id. at 18.
    - 10 -
    Here, the government concedes that the receipt and possession convictions
    are predicated on the same child pornography material. Aplee. Br. at 21 n.5
    (noting that the Superseding Indictment, jury instructions, and the prosecution’s
    opening and closing arguments “all referred to only one set of images when
    discussing both charges”). Sentencing Mr. Dunn on the possession and receipt
    counts for the same conduct therefore violates the Double Jeopardy Clause. We
    thus have no problem concluding that there has been plain error, 
    Frierson, 698 F.3d at 1270
    , and accordingly reverse and remand to the district court with
    instructions to vacate one of Mr. Dunn’s convictions. See Rutledge v. United
    States, 
    517 U.S. 292
    , 301–02, 307 (1996).
    C.    Special Conditions of Supervised Release Bearing on Employment
    Mr. Dunn also challenges the imposition of a special condition of
    supervised release mandating his participation in the Probation and Pretrial
    Services’ Computer and Internet Monitoring Program (monitoring program).
    Both parties agree that the condition is an occupational restriction, as Mr. Dunn
    was previously employed as both a computer teacher and computer technician.
    The question we now consider is whether the district court made the necessary
    findings to support the imposition of such restriction. Because he did not object
    to the imposition of this condition at sentencing, we review this challenge only
    for plain error. United States v. Burns, No. 13–5045, 
    2014 WL 7381055
    , at *1
    (10th Cir. Dec. 30, 2014).
    - 11 -
    As part of Mr. Dunn’s 25-year term of supervised release, the district court
    imposed a number of standard and special 
    conditions. 1 Rawle at 1044
    –45. The
    monitoring program imposes a number of robust restrictions on Mr. Dunn’s
    ability to use and access both computers and the Internet, and permits Probation
    to monitor that use. Among other things, the monitoring program: permits Mr.
    Dunn to use or possess only one computer at home or work; grants Probation
    permission to install monitoring software on “any computer [Mr. Dunn is]
    authorized to use”; requires Mr. Dunn to “notify all individuals that have access
    to [his] computer system that it is subject to monitoring and/or search/seizure”;
    limits his use to computer hardware and software that has been specifically pre-
    approved by Probation; and prohibits him from changing, re-installing, or
    upgrading the operating system on any computer he is authorized to use. 2 R.
    Supp. Several restrictions allow Mr. Dunn to engage in otherwise proscribed
    conduct if he obtains the prior approval of Probation.
    While district courts have broad discretion to impose conditions of
    supervised release, that discretion is circumscribed by statutory and constitutional
    limitations. United States v. Mike, 
    632 F.3d 686
    , 692 (10th Cir. 2011). As a
    starting point, conditions of supervised release must comport with the
    requirements set forth in 18 U.S.C. § 3583(d). 1 Additionally, conditions of
    1
    Pursuant to § 3583(d), conditions of supervised release must:
    [1] be reasonably related to at least one of the following: the nature
    - 12 -
    release that impinge on a defendant’s ability to seek, obtain, and maintain
    employment are subject to “special scrutiny,” the standards of which are set forth
    in U.S.S.G. § 5F1.5. United States v. Butler, 
    694 F.3d 1177
    , 1184 (10th Cir.
    2012). A sentencing court seeking to impose occupational restrictions must first
    determine that:
    (1) a reasonably direct relationship existed between the defendant’s
    occupation, business, or profession and the conduct relevant to the
    offense of conviction; and
    (2) imposition of such a restriction is reasonably necessary to protect
    the public because there is reason to believe that, absent such
    restriction, the defendant will continue to engage in unlawful conduct
    similar to that for which the defendant was convicted.
    U.S.S.G. § 5F1.5. Even if this determination is made, the court “may only impose
    the condition ‘for the minimum time and to the minimum extent necessary to
    protect the public.’” 
    Butler, 694 F.3d at 1184
    (quoting U.S.S.G. § 5F1.5(b)).
    This court has stated that “[a] district court’s duty to specifically find that a
    and circumstances of the offense, the defendant’s history and
    characteristics, the deterrence of criminal conduct, the protection of
    the public from further crimes of the defendant, and the defendant’s
    educational, vocational, medical, or other correctional needs.
    [2] . . . involve no greater deprivation of liberty than is reasonably
    necessary to achieve the purpose of deterring criminal activity,
    protecting the public, and promoting the defendant’s rehabilitation.
    [3] . . . be consistent with any pertinent policy statements issued by
    the Sentencing Commission.
    
    Mike, 632 F.3d at 692
    .
    - 13 -
    restriction is minimally restrictive is mandatory,” and has “consistently vacated
    conditions that interfere with a defendant’s occupation when no such finding is
    made.” 
    Id. (emphasis added).
    The first two requirements of plain error review—(1) an error, (2) that is
    plain—are easily satisfied here. “Our precedents unambiguously require
    supporting findings when courts impose special conditions of supervised release.”
    Burns, 
    2014 WL 7381055
    , at *2. Although the government would prefer us to
    infer from the imposition of the computer restrictions that the district court
    implicitly made the required findings, we refuse to do so in light of our command
    that district courts must make specific findings to justify these types of
    conditions. See 
    Butler, 694 F.3d at 1184
    .
    Mr. Dunn must also show that the district court’s error affects both (3) his
    substantial rights and (4) the fairness, integrity, or public reputation of the
    judicial proceedings. He has made such a showing.
    “An error affects substantial rights if there is a reasonable probability that
    the error affected the outcome of the proceedings.” Burns, 
    2014 WL 7381055
    , at
    *2. In this context, we ask whether there is a reasonable probability that, but for
    the court’s error, Mr. Dunn would have received a lesser sentence. 
    Id. Such a
    probability exists here. Even assuming there is enough support in the record to
    satisfy § 5F1.5’s requirements that there be a “reasonably direct relationship”
    between Mr. Dunn’s occupation and the offense of conviction and that the
    - 14 -
    condition is “reasonably necessary to protect the public” from a risk of re-
    offending, the record is devoid of any support as to whether the district court
    found such a condition to be minimally restrictive in light of Mr. Dunn’s
    occupation. In United States v. Sunday, 447 F. App’x 885, 889–90 (10th Cir.
    2012) (unpublished), we vacated similar computer use restrictions on plain error
    review where the district court failed to make the necessary findings. There, we
    expressed concern that the restriction “would seriously impair” the defendant’s
    ability to continue in his career as a computer repairman and, as a second-order
    effect, “make it more difficult for him to pay his mandatory monthly restitution.”
    
    Id. at 890;
    see also 
    Butler, 694 F.3d at 1185
    .
    After a careful review of the record, we cannot conclude that the district
    judge found—either explicitly or implicitly—that compliance with the monitoring
    program for the entire term of supervised release was minimally restrictive. As
    Mr. Dunn correctly points out, a number of the judge’s statements at the
    sentencing hearing suggest exactly the opposite. At that hearing, the judge stated
    that he did not “believe there’s a substantial likelihood that Mr. Dunn will
    reoffend” and found that he was “extraordinarily 
    remorseful.” 2 Rawle at 105
    . The
    judge made no specific findings with regard to the special conditions of
    supervised release, instead asserting that they were “appropriate given the facts
    and circumstances of this case.” 
    Id. at 107.
    It is unclear to us whether the district
    judge even considered the effect of the computer monitoring program on Mr.
    - 15 -
    Dunn’s prospects for future employment or his ability to pay restitution to his
    victims. Perhaps the district court would make such findings, “[b]ut, the record is
    not sufficient for us to make this determination in the first instance.” Burns, 
    2014 WL 7381055
    , at *2.
    Imposing such an onerous restriction, especially when the restriction will,
    for all intents and purposes, materially impact the defendant’s ability to obtain
    work, affects the fairness, integrity, and public reputation of judicial proceedings
    when the district court fails to make any special findings with respect to that
    restriction. Sunday, 447 F. App’x at 890; see United States v. Pruden, 
    398 F.3d 241
    , 251 (3d Cir. 2005). Thus, “given the required scrutiny which we give to
    occupational restrictions, we conclude we must vacate the occupational restriction
    relating to computer use and monitoring and remand for further consideration,
    including making the findings required before imposition of any occupational
    restriction.” Sunday, 447 F. App’x at 890. On remand, the district court should
    vacate the restrictions and reconsider the matter with proper findings.
    D.    Restitution Under 18 U.S.C. § 2259 After Paroline
    Finally, Mr. Dunn challenges the district court’s order requiring him to pay
    $583,955 in restitution to one of the victims depicted in the child pornography he
    possessed and distributed. The government agrees with Mr. Dunn that in light of
    the Supreme Court’s recent decision in Paroline v. United States, 
    134 S. Ct. 1710
    (2014), we should vacate the district court’s order and remand for proceedings
    - 16 -
    consistent with Paroline. We agree that the district court’s restitution order is
    inconsistent with Paroline. On remand, the restitution should be vacated and
    considered res nova.
    Following Mr. Dunn’s convictions, one of the children depicted in images
    of child pornography he possessed and distributed, “Vicky,” filed a request for
    restitution pursuant to 18 U.S.C. § 2259. Vicky sought $583,955 from Mr. Dunn,
    which represented the amount of her total losses minus the amount of restitution
    she had previously received from other defendants by way of restitution. The
    district court denied Mr. Dunn’s motion seeking “to compel Vicky to produce a
    more up-to-date economic report regarding her damages and regarding the
    damages Mr. Dunn caused as a result of his underlying criminal behavior.” 1 R.
    Supp. at 31. The district court found that the “exhibits supporting Vicky’s
    restitution request are credible and accurately establish the extent of her losses
    from child pornography.” 
    Id. The district
    court concluded, based on its findings of fact and conclusions
    of law, that “there is a sufficient nexus between Dunn’s crimes and all of the
    losses suffered by Vicky to award restitution for those losses.” 
    Id. at 32.
    Relying
    heavily on the Seventh Circuit’s decision in United States v. Laraneta, 
    700 F.3d 983
    (7th Cir. 2012), the district court concluded that because Mr. Dunn was a
    distributor of Vicky’s images, his acts were of such a nature that he should be
    held jointly and severally liable for the entirety of Vicky’s injuries. 1 R. Supp. at
    - 17 -
    34–35. The district court also found its order to be consistent with this court’s
    decision in Benoit, 
    713 F.3d 1
    , where we held that a restitution order pursuant to
    § 2259 requires a finding that the defendant proximately caused the victim’s
    injuries.
    Paroline resolved a circuit split on the question of “what causal relationship
    must be established between the defendant’s conduct and a victim’s losses for
    purposes of determining the right to, and the amount of, restitution under § 
    2259.” 134 S. Ct. at 1716
    . After holding that § 2259 requires a showing of proximate
    cause, the Court turned its attention to what it considered “the primary
    problem”—what “causation in fact” standard to apply in these cases. 
    Id. at 1722.
    In other words, because the statute requires a causal nexus between a particular
    defendant’s conduct and the victim’s losses, how should courts determine the
    amount of restitution owed by a single defendant—likely unknown to the victim
    in many, if not most, cases—to the victim, when that defendant is one of
    potentially thousands of individuals who has engaged in possession or distribution
    of the images. 
    Id. Because of
    the “somewhat atypical causal process underlying the losses” in
    the child pornography context, the Court rejected the “traditional way to prove
    that one event was a factual cause of another.” 
    Id. The Court
    instead embraced
    an “aggregate causation” theory, premised on the fact that one single cause may
    be neither sufficient nor necessary to bring about a certain result, yet still may be
    - 18 -
    considered a cause in fact of that result. 
    Id. at 1724–26.
    Borrowed from tort
    principles, this theory has limitations, especially when transplanted to the
    criminal context. 
    Id. at 1724.
    Thus, while a single defendant who possessed or
    even trafficked in child pornography undoubtedly “plays a part in sustaining and
    aggravating this tragedy,” 
    id. at 1726,
    the Court outright rejected the notion that
    any one such defendant should be held liable for “the conduct of thousands of
    geographically and temporally distant offenders acting independently, and with
    whom the defendant had no contact,” 
    id. at 1725.
    Applying an aggregate causation model, but with important limiting
    principles, the Court provided:
    [W]here it can be shown both that a defendant possessed a victim’s
    images and that a victim has outstanding losses caused by the
    continuing traffic in those images but where it is impossible to trace
    a particular amount of those losses to the individual defendant by
    recourse to a more traditional causal inquiry, a court applying § 2259
    should order restitution in an amount that comports with the
    defendant’s relative role in the causal process that underlies the
    victim’s general losses.
    
    Id. at 1727
    (emphasis added). For an offender like Paroline, who possessed two
    images of the particular victim seeking restitution, the contribution to the causal
    process is “very minor,” 
    id. at 1725,
    and therefore the restitution order should be
    neither “severe” nor “token.” 
    Id. at 1727
    .
    The Court acknowledged that setting a proper restitution award under this
    standard will involve both “discretion and estimation,” 
    id. at 1729,
    and noted that
    - 19 -
    a “precise mathematical inquiry” would be ill-suited for the time being, 
    id. at 1728.
    Rather, a district court “must assess as best it can from available evidence
    the significance of the individual defendant’s conduct in light of the broader
    causal process that produced the victim’s losses.” 
    Id. at 1727
    –28. The Court
    cited a number of factors that district courts should consider as “rough
    guideposts” in “determining an amount that fits the offense.” 
    Id. at 1728.
    After
    determining the “amount of the victim’s losses caused by the continuing traffic in
    the victim’s images,” a district court should consider, among other things:
    the number of past criminal defendants found to have contributed to
    the victim’s general losses; reasonable predictions of the number of
    future offenders likely to be caught and convicted for crimes
    contributing to the victim’s general losses; any available and
    reasonably reliable estimate of the broader number of offenders
    involved (most of whom will, of course, never be caught or
    convicted); whether the defendant reproduced or distributed images
    of the victim; whether the defendant had any connection to the initial
    production of the images; how many images of the victim the
    defendant possessed; and other facts relevant to the defendant’s
    relative causal role.
    
    Id. It is
    clear that the district court’s order requiring Mr. Dunn to pay $583,955
    cannot stand in light of Paroline. That order clearly holds Mr. Dunn liable for the
    “the conduct of thousands of geographically and temporally distant offenders
    acting independently, and with whom [Mr. Dunn] had no contact,” in
    contravention of Paroline’s guidance. 
    Id. at 1725.
    This conclusion is
    demonstrated by the fact that Vicky’s total losses were approximately $1.3
    - 20 -
    million and Mr. Dunn, a single defendant, was held jointly and severally liable for
    nearly half of her losses. And while the district court properly acknowledged that
    Mr. Dunn was not a mere possessor, but was convicted as well for distributing
    child pornography, the court placed near dispositive reliance on that fact in
    fashioning the restitution award. See 1 R. Supp. at 32, 35–36. Indeed, it is
    inherently logical to view distributors as more culpable in the causal process than
    “mere” possessors; however, we think it important to note that not all distributors
    should be placed on the same footing. As noted, a reasonable jury could conclude
    that Mr. Dunn distributed the contraband by knowingly placing it into a shared
    folder on a peer-to-peer network. But in assessing Mr. Dunn’s relative role in the
    causal process for restitution purposes, the district court should consider the facts
    underlying that conviction—i.e., did the government show that others had actually
    downloaded files from Mr. Dunn and, if so, had only one or two other people
    downloaded those images from him, or had hundreds or thousands over a period
    of years. We think these are proper considerations in light of Paroline’s guidance
    that the amount of restitution “be a reasonable and circumscribed award imposed
    in recognition of the indisputable role of the offender in the causal process
    underlying the victim’s losses and suited to the relative size of that causal role.”
    
    Id. at 1727
    (emphasis added).
    Finally, the parties dispute whether we should overturn the district court’s
    factual finding that Vicky’s total losses—the starting point from which Mr.
    - 21 -
    Dunn’s restitution amount shall be determined—are $1,330,015. According to
    Mr. Dunn, “the measure of Vicky’s damages under the rule in Paroline is the
    harm associated with ‘the continuing traffic in [her] images,’ a total from which
    the harms caused by her initial abuse have been subtracted.” Aplt. Br. at 26
    (quoting 
    Paroline, 134 S. Ct. at 1722
    ). Mr. Dunn contends that “[t]he expert
    reports regarding Vicky’s damages do not clearly distinguish the primary harms
    associated with her original abuse from those secondary harms flowing from the
    dissemination of images of her online,” 
    id. at 27,
    and therefore the district court’s
    “starting point” was flawed. The government does not challenge Mr. Dunn’s
    assertion regarding the expert report. Rather, it argues (a) that Paroline does not
    require district courts to consider only those losses caused by the continued
    trafficking in a victim’s images, and (b) Mr. Dunn waived this argument by
    failing to object at sentencing. Aplee. Br. at 31–32.
    We acknowledge that Paroline did not resolve this precise question. 134 S.
    Ct. at 1722 (“Complications may arise in disaggregating losses sustained as a
    result of the initial physical abuse, but those questions may be set aside for
    present purposes.”). But the clear rationale of Paroline is that a defendant should
    be held accountable for the measure of losses that he individually has caused. We
    think it inconsistent with “the bedrock principle that restitution should reflect the
    consequences of the defendant’s own conduct” to hold Mr. Dunn accountable for
    those harms initially caused by Vicky’s abuser. 
    Id. at 1725.
    Thus, to the extent
    - 22 -
    that the district court relied on an expert report that did not disaggregate these
    harms, the district court’s adoption of $1.3 million as the total measure of
    damages cannot stand. Mr. Dunn’s objection, requesting a “more up-to-date
    economic report regarding her damages and regarding the damages that Mr. Dunn
    caused as a result of his underlying criminal behavior,” 1 R. Supp. at 31, was
    sufficient to preserve this argument. Accordingly, on remand, the restitution
    order should be vacated, further proceedings conducted, and the matter considered
    anew with the above guidance.
    AFFIRMED in part, REVERSED in part, and REMANDED.
