A new report says one of Meta’s advertising partners in China was connected to thousands of Facebook and Instagram ads promoting so-called nudify apps. The findings were attributed to the Tech Transparency Project, a nonprofit group that examines major technology companies and their business practices.

The report puts fresh attention on how ads are approved and distributed across Meta’s platforms. Nudify apps, which are marketed as tools that can digitally alter images to make people appear unclothed, have drawn criticism because of privacy, safety and abuse concerns.

According to the report summary, the ads were placed through a Meta partner operating in China, raising questions about oversight within the company’s advertising network. The issue is likely to intensify scrutiny of how Meta reviews advertisers, monitors partners and enforces rules around harmful or exploitative content.

The allegations also add to broader debates over platform responsibility and ad moderation on Facebook and Instagram. While the trimmed report excerpt does not include Meta’s full response, the claims highlight the challenges large tech companies face in stopping problematic ads before they reach users.
