Remove DeepNude content from 4chan

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 4chan, 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 4chan specifically, 4chan boards including /b/ and /soc/ have historically been primary distribution points for ncii. threads expire quickly but content is preserved in third party archives that mirror entire boards.

How removal proceeds

4chan threads expire automatically. Active removal requires emailing dmca@4chan.org with the thread URL. Archive sites such as warosu and archive.4plebs require separate filings. 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.
