Revenge Porn / Image-Based Sexual Abuse
✎ 本文編集 (admin) 🖼 画像編集 (admin)A term born out of a tabloid framing that survivors and scholars have spent a decade working to replace. The activity remains the same: the non-consensual distribution of someone’s intimate images, intended to harm or used to harm. The framing has shifted toward language that centres the survivor and recognises the activity as a form of sexual abuse, not as the spurned-partner story the early revenge porn label implied.
Overview
Revenge porn is the popular term, dating from the early 2010s, for the non-consensual distribution of intimate images. The contemporary academic and policy term is image-based sexual abuse (IBSA), introduced by the British legal scholars Clare McGlynn and Erika Rackley in the mid-2010s as part of a deliberate move to centre the harm caused rather than the motive of the perpetrator. Non-consensual intimate imagery (NCII) is the term used in much United States platform-policy and federal-legislative work. The phenomenon covers the distribution of photographs and video, the redistribution of legitimately-created intimate material without consent, the malicious manipulation of imagery (including AI-generated deepfake sexual content), and the threat to distribute as a tool of coercion.
The legal response has developed rapidly. Between 2013 and 2025, most major jurisdictions enacted specific criminal offences targeting the conduct. The principal legal frameworks are reviewed below, with Japan’s 2014 statute, the UK Criminal Justice and Courts Act 2015, the US patchwork of state criminal law combined with the federal civil action in 15 U.S.C. § 6851 (2022) and the federal TAKE IT DOWN Act (2025), and the EU Digital Services Act 2022 as the main reference points.
The terminological shift
The term revenge porn entered public discourse in the early 2010s, most prominently through the website Is Anyone Up? (run by Hunter Moore, 2010-2012), which collected and published intimate images without subject consent. Tabloid framing of the issue used revenge porn as the operative label, and the term captured something of the perceived motive of perpetrators in early high-profile cases.
The term has been criticised on two grounds. First, revenge misreads the motive in many cases: a substantial fraction of distributions are carried out for entertainment, profit (paid sites), or social-status display within male peer groups, with no specific revenge component. Second, porn implies consensual sexual content, while the defining feature of the conduct is the absence of consent to distribution.
The replacement term image-based sexual abuse (IBSA), developed by Clare McGlynn, Erika Rackley, and their collaborators, addresses both issues. Image-based captures the digital-image medium of the abuse; sexual abuse captures the harm without implying consent. The term has been adopted progressively by academic and policy writing in the United Kingdom, Australia, and (increasingly) the European Union, and is the preferred terminology in the contemporary scholarly literature. Revenge porn remains the more recognised term in public discourse; image-based sexual abuse is the preferred analytical and legal term.
Japan: the 2014 Act
The triggering event for Japanese legislation was the Mitaka stalker-murder case of October 2013, in which an eighteen-year-old female high-school student was killed by her former boyfriend. The investigation revealed that the perpetrator had posted intimate images of the victim on social media before the killing. The case galvanised public and parliamentary opinion, and within thirteen months Japan enacted the Act on the Prevention of Damage Caused by the Provision of Private Sexual Image Records (Act No. 126 of 2014, commonly known as the Revenge Porn Prevention Act), in force from 27 November 2014.
Definitions
The Act defines private sexual image records in Article 2(1) in three categories: (1) images depicting sexual intercourse or quasi-sexual-intercourse conduct, (2) images depicting touching of genitals or having genitals touched, in a manner intended to arouse or stimulate sexual desire, and (3) images of partially or fully unclothed persons in which a sexual body part is specifically exposed or emphasised in a manner intended to arouse or stimulate sexual desire. The Act’s protection applies to images created in the context of consensual private filming (typically between intimate partners) and to images created without the subject’s consent. Commercially distributed adult video and content the subject themselves intended for public distribution are not within the Act’s protective scope.
Offences
Article 3(1) creates the principal offence: providing private sexual image records to an unspecified or numerous third parties, or publicly displaying them, in a manner by which the subject can be identified by third parties, by means of an electrical communications line (internet). The penalty is up to three years’ imprisonment or a fine up to 500,000 yen. Article 3(2) creates a subsidiary offence for providing such records to a third party with the intent that the third party commit the principal offence (one year imprisonment or 300,000 yen fine).
Survivor-centred procedural features
The Act sets the offence as a shinkokuzai (relative-prosecution offence): prosecution requires the victim’s complaint, preserving the survivor’s control over whether the case proceeds. Article 4 provides a fast-track removal procedure: where a victim demands that an internet platform remove infringing material, the standard seven-day waiting period for sender objection under the Provider Liability Limitation Act is shortened to two days. This procedural acceleration is one of the operationally significant features of the Japanese framework, designed to limit the cascade of redistribution that occurs in the first hours after publication.
Enforcement
National Police Agency statistics report rapid growth in case numbers since enactment: 32 cases in the partial 2014 year (November-December), 521 in 2015, and figures in the 600-1500 range across subsequent years, with smartphones and social-media expansion driving the long-term increase.
United Kingdom
The United Kingdom introduced a specific offence in Section 33 of the Criminal Justice and Courts Act 2015, criminalising the disclosure of private sexual photographs and films without consent and with intent to cause distress, with a maximum penalty of two years’ imprisonment. The Act has subsequently been amended and supplemented.
The Domestic Abuse Act 2021 extended the framework to cover threats to disclose intimate images (the threats element captures the use of such images as a coercive tool within abusive relationships). The Domestic Abuse Act 2021 also recognises image-based abuse as a form of domestic abuse rather than as a separate-category sexual-conduct offence, formalising the survivor-centred reframing that academic writing on IBSA had advocated.
Successive reforms have responded to the deepfake issue: the Online Safety Act 2023 introduced offences covering the sharing of altered intimate images and the threat to share such images, and proposed legislation under consideration covers the creation of intimate deepfakes regardless of distribution.
United States
US law on non-consensual intimate imagery developed in two waves: a long state-level wave that began in 2013, followed by federal action between 2022 and 2025.
At the state level, the wave began with California’s SB-255 (October 2013), and by May 2025 all fifty states and the District of Columbia had enacted specific NCII criminal legislation, with South Carolina the final state to do so. The state statutes vary substantially in scope, intent requirements (some require intent to harass or harm; others reach reckless or knowing disclosure without that overlay), and penalties, producing a complex patchwork that the later federal action was intended to backstop rather than displace.
The first federal civil remedy arrived with the 2022 reauthorisation of the Violence Against Women Act (VAWA), which created a civil cause of action at 15 U.S.C. § 6851 for the disclosure, in or affecting interstate commerce, of an intimate visual depiction of an identifiable person where the discloser knew or recklessly disregarded the absence of consent. The provision applies to disclosures made on or after 1 October 2022 and offers statutory damages of up to $150,000, plus actual damages, attorneys’ fees, and injunctive relief. The 2022 framework provides civil remedy only; it does not create a federal criminal offence. (Earlier proposals such as the Stopping Harmful Image Exploitation and Limiting Distribution Act — the SHIELD Act, repeatedly introduced from 2016 onwards by Rep. Jackie Speier and others — would have created a federal criminal offence but were never enacted.)
The first federal criminal statute targeting non-consensual intimate imagery is the Tools to Address Known Exploitation by Immobilizing Technological Deepfakes On Websites and Networks Act (TAKE IT DOWN Act), enacted as Public Law 119-12 after passage of S.146 (House 409-2, Senate by unanimous consent) and signed by President Trump on 19 May 2025. The Act creates a federal criminal offence for the knowing publication, via an interactive computer service, of an intimate visual depiction or a digital forgery (i.e. an AI-generated deepfake) of an identifiable individual, with penalties of up to two years’ imprisonment for adult depictions and up to three years for depictions of minors. The criminal provisions took effect on enactment. The Act also imposes a notice-and-removal regime on covered platforms: upon receipt of a valid notice from the depicted individual, the platform must remove the matter as soon as possible and in any event within forty-eight hours, and must operate the notice procedure under Federal Trade Commission enforcement. The platform-side compliance deadline is 19 May 2026, one year after enactment.
Together the VAWA 2022 civil cause of action, the TAKE IT DOWN Act 2025 criminal offence and notice-and-removal regime, and the state-by-state criminal patchwork constitute the contemporary US framework.
European Union
The Digital Services Act (Regulation 2022/2065) provides platform-level obligations across the EU, requiring large online platforms to operate effective notice-and-action procedures for illegal content, including non-consensual intimate imagery. The DSA is platform-focused rather than offender-focused, addressing the systemic redistribution problem rather than the individual perpetrator. Member-state criminal law (Germany’s 2020 reform, France’s 2020 amendments, Italy’s 2019 Codice Rosso) provides the offence-level framework.
A 2024 EU directive on combating violence against women includes specific provisions on non-consensual sharing of intimate or manipulated material, harmonising treatment across the bloc.
South Korea
South Korea’s response has been particularly intense, driven by the social-movement response to the molka (hidden-camera filming) epidemic that became a central feminist mobilisation issue in 2018. The Act on Special Cases concerning the Punishment of Sexual Crimes, particularly Article 14, was strengthened in 2018 and 2020 to impose penalties of up to seven years’ imprisonment for non-consensual filming and distribution, including substantial penalties for distribution-for-profit. The South Korean framework is one of the more punitive globally and is sometimes cited as an example of strong survivor-protective legislation.
Deepfakes and AI-generated content
The rise of generative AI in the late 2010s and early 2020s has produced a new category of harm: AI-generated intimate imagery of real people. The 2024 cases involving non-consensual deepfake intimate content of public figures and private individuals have driven legislative responses worldwide.
Most existing IBSA frameworks were drafted before generative AI was operationally available and have required interpretive or legislative adjustment. The UK Online Safety Act 2023 amendments and several US state statutes have explicitly extended to altered and generated imagery. Japan’s 2014 statute requires the subject’s own depicted form as a definitional element, and the application to deepfakes is a contested interpretive question that has been the subject of multiple legislative-amendment proposals.
Platform response
Major platforms (Google, Meta, X/Twitter, Reddit) operate notice-and-takedown procedures for non-consensual intimate imagery. Google has accepted search-result delisting requests for NCII since 2015. Meta operates a StopNCII.org hash-matching service (in partnership with the UK Revenge Porn Helpline) that allows survivors to register intimate images and have them blocked from upload across the partner platforms. The hash-matching architecture is one of the more effective contemporary tools, particularly for limiting cascade redistribution after a first publication.
The structural problem in platform response is the speed of redistribution: an image posted on one platform is typically copied and reposted across many others within hours, and effective response requires coordinated action across the platform ecosystem.
Victim impact
The clinical and survey literature on IBSA has documented severe impacts on survivors. Psychological consequences (post-traumatic stress, anxiety, depression, suicidal ideation), social consequences (relationship breakdown, social withdrawal, employment loss), and professional consequences (career-track impacts, particularly for women in public-facing roles) are all well documented. The literature now treats IBSA as a form of sexual violence rather than as a discrete category of digital misconduct, and survivor-support organisations (Revenge Porn Helpline in the UK, Cyber Civil Rights Initiative in the US, the Yorisoi service in Japan) provide specialised support modelled on the broader sexual-violence-support framework.
Theoretical and policy debates
The contemporary IBSA literature contains several ongoing debates.
The relationship to broader sexual-violence frameworks is the principal theoretical question. McGlynn and Rackley argue for full integration of IBSA into the sexual-violence-and-abuse framework, treating image-based abuse as a sub-category of sexual abuse rather than as a separate digital-conduct category. The integration position has substantial influence in academic and policy writing.
Platform liability and the Section 230 (United States) immunity framework is an active US policy debate. The European DSA approach, which imposes obligations on platforms directly, is sometimes contrasted with the US Section-230 approach, which provides broad immunity for user-generated-content platforms. The US debate has produced ongoing legislative-reform proposals.
The criminal-justice-versus-civil-remedy balance varies by jurisdiction. The Japanese, UK, and South Korean frameworks emphasise criminal enforcement; the US framework relies more heavily on civil remedies and platform takedown. Cross-jurisdictional empirical comparison of effectiveness remains an open area of research.
