The combined situation

Civitai is the dominant hosting platform for Stable Diffusion fine tunes and LoRA adapters, including a large catalog of celebrity and public figure LoRAs that enable NCII generation. When Civitai 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

Civitai hosts thousands of LoRA models trained on identifiable individuals without their consent. Each removed model prevents future generation rather than addressing existing content. 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 Civitai is documented through civitai itself does not generate images, but hosts the model files used by other tools, which strengthens the takedown notice and supports parallel legal action.
