Remove DeepNude content from Mastodon

The combined situation

DeepNude was the original 2019 nudify application that established the category. It was shut down by its developer after public outcry, but the model weights were leaked and now power dozens of clone services. When DeepNude 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

DeepNude derivative services proliferate under different names but produce visually identifiable output. Hash matching against known DeepNude derivative samples accelerates platform removal under 47 USC 223a. 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 DeepNude is documented through deepnude outputs and direct derivatives display a characteristic 512x512 base resolution upscaled to higher dimensions, producing a recognizable softness in fine detail, which strengthens the takedown notice and supports parallel legal action.
