The combined situation

UndressAI.tools operates primarily through Telegram bots that accept photo uploads in private message and return processed output. It is one of the largest Telegram based nudify operations. When UndressAI.tools 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

Telegram bot architecture makes UndressAI.tools nearly invisible to standard web monitoring. Bots can be reinstantiated under new usernames within minutes of a takedown. 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 UndressAI.tools is documented through undressai, which strengthens the takedown notice and supports parallel legal action.
