The combined situation

Nudify.online is a freemium nudify service that allows three free outputs per day per IP. The pay tier removes watermarking and increases output resolution. When Nudify.online 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

Nudify.online has no terms of service, no contact information, and no age verification. The service is accessible from school networks in most United States districts because it has not been added to standard content filtering blocklists. 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 Nudify.online is documented through free tier outputs carry a faint nudify watermark in the lower right corner, which strengthens the takedown notice and supports parallel legal action.
