An investigation by the Tech Transparency Project (TTP) reveals that Meta failed to detect 332 advertisements on Facebook and Instagram containing AI-generated child sexual abuse material (CSAM) this year. Many of these ads promoted "nudify" applications, primarily developed in China, which use AI to transform images of real children into explicit sexual content. TTP identified specific instances where ads used photos of a European royal, a 14-year-old Instagram influencer, and a preteen in stock photos to create graphic, animated videos of sexual acts or molestation. Despite Meta's claims of deploying new detection systems following an August report, researchers found hundreds of new violations. The ads reached significant audiences, including over 29,000 people in the EU and 6,800 in the UK, with approximately 80 percent of impressions occurring in the US. Meta has been criticized for inconsistent enforcement and delayed removals; in some cases, ads continued to run for days after being flagged, and Meta failed to mark several ads as policy violations until prompted by TTP. Furthermore, TTP found that three Chinese ad reseller partners—GIMC, Meetsocial, and BlueFocus—ran ads containing CSAM content, raising concerns regarding Meta's oversight of lucrative international advertising streams.
