The combined situation

Undress.app is one of the highest traffic nudify services. It markets itself through aggressive paid social campaigns and operates a referral program that incentivizes redistribution. When Undress.app output appears on Bluesky, removal proceeds through the statutory takedown process under 47 USC 223a combined with source attribution to strengthen the legal claim.

Why this combination is high risk

Undress.app has been observed using stolen Instagram and TikTok photographs in its marketing previews. It has been the subject of UK Information Commissioner's Office inquiry since 2024. On Bluesky specifically, bluesky's open atproto network allows third party clients and appviews to display the same content. a removal from the official bluesky app does not always remove from third party clients.

How removal proceeds

Bluesky accepts NCII reports through its in app moderation flow and through its trust and safety email. The PDS architecture means content is hosted on individual personal data servers in addition to the network appView. Source attribution to Undress.app is documented through undress, which strengthens the takedown notice and supports parallel legal action.
