Remove Promptchan content from Bluesky

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 Bluesky, 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 Bluesky specifically, bluesky's open atproto network allows third party clients and appviews to display the same content. a removal from the official bluesky app does not always remove from third party clients.

How removal proceeds

Bluesky accepts NCII reports through its in app moderation flow and through its trust and safety email. The PDS architecture means content is hosted on individual personal data servers in addition to the network appView. 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.
