Meta's Ad Library Hosted Dozens of AI-Generated Child Sexual Abuse Material
Key Takeaways
- ▸Over 50 paid ads containing AI-generated CSAM were discovered in Meta's ad library and had been approved by Meta's systems
- ▸Ads reached thousands of accounts across multiple countries; at least one reached 2,563 European accounts before discovery
- ▸The ads ran for months (November 2025–August 2026) without detection by Meta's automated systems, despite Meta's transparency policies
Summary
Researchers at the Tech Transparency Project discovered over 50 paid advertisements containing AI-generated child sexual abuse material (CSAM) running on Meta's platforms between November 2025 and August 2026. The ads, which appeared on Facebook, Instagram, Messenger, and Threads, were reviewed and approved by Meta before publication and included explicit imagery of minors alongside sexually suggestive text, with some linking to "nudify" or undressing apps. According to Meta's ad transparency library, at least one ad reached 2,563 accounts across European countries including France, Germany, Ireland, Italy, the Netherlands, Spain, Sweden, and the United Kingdom.
The Tech Transparency Project researchers reported the findings to the National Center for Missing and Exploited Children's CyberTipline after discovering the ads during an investigation into nudify app advertising on Meta. Katie Paul, director of TTP, stated that the ads "made no effort to mask the images or hide what they were promoting" and stressed that these were ads "reviewed, approved, and allowed to run by Meta." Meta removed the advertisements after being contacted by WIRED, claiming that many ads had been disabled before the publication reached out, and stating that "sexual exploitation is horrific, and we work aggressively to keep it off our platform."
This discovery marks the second discovery of CSAM-linked ads on Meta platforms in recent weeks, raising questions about the effectiveness of Meta's content moderation systems and its ability to detect synthetic abuse material generated by AI.
