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 Baidu, 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 Baidu specifically, baidu indexes content from chinese platforms that are otherwise inaccessible to western search. ncii content originating in or mirrored to chinese forums is frequently discoverable only through baidu.

How removal proceeds

Baidu accepts removal requests through its dedicated complaints portal in Mandarin. Baidu Tieba and Baidu Image Search 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.
