Remove Promptchan content from 4chan

The combined situation

Promptchan is a community oriented explicit image generator with a public gallery. The service publishes user generations as a feed which accelerates redistribution. When Promptchan 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

Public gallery distribution means Promptchan content reaches search engine indexes within days of generation. Search engine deindexing is essential alongside source removal. 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 Promptchan is documented through promptchan outputs display the generation prompt and seed in metadata when downloaded directly from the platform, which provides definitive identification of the source service, which strengthens the takedown notice and supports parallel legal action.
