The combined situation

ClothOff is a single purpose nudify service that takes a clothed photograph and returns a nude reconstruction. It has been the subject of formal complaints by Spanish, French, and Italian regulators since 2023. When ClothOff output appears on Mastodon, 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

ClothOff has been linked to multiple school harassment cases involving minors in Spain, the United States, and the United Kingdom. The service has no age verification and outputs are routinely shared on Telegram and Discord. On Mastodon specifically, federated content spreads across multiple instances through reposts and replies. removing from the originating instance does not remove from the cached copies on every instance that federated the post.

How removal proceeds

Mastodon is federated across thousands of independent instances. Removal requires identifying the specific instance hosting the content and contacting that instance's admin directly. Source attribution to ClothOff is documented through clothoff outputs typically display a soft skin gradient transition along the original clothing edge, slight asymmetry in nipple placement, and a faint moire pattern in the lower abdomen, which strengthens the takedown notice and supports parallel legal action.
