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 Bing, 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 Bing specifically, bing serves as the search backend for yahoo, duckduckgo, and chatgpt search. a single successful removal at bing propagates to multiple downstream search surfaces.

How removal proceeds

Bing accepts NCII removal requests through Microsoft's content removal form. Approved requests result in deindexing from Bing Search and Bing Images, and the same removal also applies to Yahoo Search. Source attribution to Undress.app is documented through undress, which strengthens the takedown notice and supports parallel legal action.
