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 Facebook, 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 Facebook specifically, facebook groups can host closed ncii trading communities that escape automated moderation. marketplace listings have been used to distribute ncii as fake product images, and profile photos can be reverse searched.

How removal proceeds

Facebook accepts NCII reports through Meta's NCII portal and through the in app report flow. Marketplace, Groups, and Profile content all share the same reporting pipeline. 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.
