Expanding on our prior analyses of problematic advertisement on Meta, we question in this report whether Facebook & Instagram violate App Stores' Terms of Service by showing users pornographic ads.

We present evidence that:

• Meta distributes ads illustrated with pornographic visuals on Facebook and Instagram, including mobile applications;
• Such pornographic content is prohibited by both App Store and Google Play policies;
• Meta has been notified, per our previous report, that their moderation systems approved sexually explicit ads;
• Meta has acknowledged such explicit content violates their policies;
• Meta has the technical capability to automatically identify these visuals as sexually explicit;
• Apple’s App Store has explicitly confirmed, pursuant to our notice, that such content violates their policies;

As such, we consider that the enforcement of Meta's policies as well as those of App Store and Google Play could warrant scrutiny under the Digital Services Act.
