Researchers report that ads displayed on Meta’s platforms included AI-generated child sexual abuse material (CSAM). According to the accounts, the issue involves more than 50 ads found in Meta’s ad-related services, where the imagery violates the company’s policies prohibiting child sexual abuse content. The researchers say some of the ads were identified as being posted or remaining on Meta properties even after Meta had been warned, suggesting weaknesses in detection or moderation processes. One report characterizes the findings as part of a broader, recurring pattern of child-safety failures over multiple years, while both accounts focus on the presence of AI-generated CSAM specifically within the ad ecosystem. The reports describe the discovery as coming from analysis of Meta’s ad libraries or ad-serving surfaces and emphasize that the identified content contravenes Meta’s stated rules. Neither account indicates that Meta publicly confirms the findings in the provided text, but both describe the same core allegation: AI-generated CSAM appears in Meta-hosted or -served advertisements.
