Meta has described new measures to detect ads that may covertly direct users to child sexual exploitation material, including AI-based checks of ad content and destinations. The company also reported actioning 33.2 million pieces of such content on Facebook and Instagram worldwide from January through June 2026, with more than 97% found before user reports.
Meta says it has added AI-based ad detection, checks of external links and stronger repeat-offender detection to its efforts to combat child sexual exploitation on Facebook, Instagram and Threads. In a report published in October 2026, the company also said it actioned 33.2 million pieces of child sexual exploitation content on Facebook and Instagram worldwide from January through June, with more than 97% found and addressed before users reported it.
Meta said the new measures followed an investigation into advertisements that appeared harmless but allegedly directed people to illegal material hosted outside its platforms. The company said it expanded the investigation beyond reported ads, disabled accounts it found to be violating its policies and blocked associated external links. It did not identify the accounts or disclose how many ads or links were involved.
The additional measures include a large language model intended to identify ad wording that may act as covert “signposting” to exploitation material, and systems that assess where an ad leads as well as what it displays. Meta said it has also added AI-assisted sweeps for ads, an AI agent to test its own defences, and strengthened detection of people attempting to open new accounts after enforcement action.
The company described these measures as additions to its existing systems. Those include automated analysis of account behaviour, matching technology such as PhotoDNA to identify known images and videos, and rules that combine classifiers and other signals to detect emerging patterns. Meta said it reports identified child sexual abuse material to the National Center for Missing & Exploited Children (NCMEC), in line with applicable law, and blocks links to external sites it identifies as hosting or creating violating material.
How Ad Checks Could Disrupt Abuse
The changes address a particular enforcement challenge: a post or advertisement may not itself contain illegal imagery but could still direct users to harmful material elsewhere. Checking destinations as well as ad content could help Meta act on that pathway, while blocking a link across posts, comments and ads may limit its circulation on the company’s services.
Meta’s figures indicate the scale of enforcement it reports, but they are company-reported totals, not an independent measure of how much exploitation occurs online or how effective the new tools are. The company said over 97% of the 33.2 million pieces actioned globally were identified before user reports. That describes the share proactively found among the content Meta actioned during the six-month period; it does not establish the tools’ accuracy or the amount of material that remained undetected.

Existing Detection and Reporting Systems
Meta said it has used PhotoDNA and other matching technology across its apps since 2011 to detect identical or near-identical copies of known child sexual abuse material. The company said it contributes newly identified hashes to its database and shares hashes with participating companies through the Tech Coalition’s Lantern program. It also uses matching technology on previews of external links.
For January-June 2026, Meta reported actioning 5.3 million pieces of child sexual exploitation content on Facebook and Instagram in India, with over 98% found before user reports. In September 2026, the company announced that it would report child safety cases directly to India’s National Cyber Crime Reporting Portal, operated by the Indian Cybercrime Coordination Centre. These numbers and descriptions come from Meta; the report does not provide an independent audit or a detailed breakdown by enforcement measure.

What the Report Does Not Show
Meta did not publish the number of ads or accounts linked to the scheme, the number of external links blocked, or how many cases were referred to authorities as a result of the investigation. It also did not provide test results showing how accurately the new AI tools identify harmful ads, how often they mistakenly flag permitted material, or whether the changes have reduced users’ exposure.
The 2026 totals cover content the company actioned, but Meta’s report does not explain how those totals compare with earlier periods or how much potentially violating material may remain undetected. The report also does not provide independent verification of its figures. The effectiveness of the new measures and their impact on exploitation networks remain unclear.

Further Enforcement and Reporting
Meta said it will continue expanding signals used to identify emerging tactics and use its red-teaming AI agent to probe its defences. It also said it will keep investigating suspected networks, removing violating content and accounts, blocking links, and reporting cases to law enforcement through applicable channels.
The company did not announce a deadline for a further update or say when it would publish performance data on the new ad checks. Future reporting would need to show how many cases the tools detect, how enforcement outcomes change over time, and what safeguards address errors. Meta’s September announcement on direct reporting in India provides a stated next step in its cooperation with authorities, but the company has not provided figures on cases reported through the portal.
