Welcome to the outbox model. The author of the post that the porn was a reply for might have damus in their outbox/inbox relay list.

My only relay at the moment is nostr.land (and Coracle does show that), which should be spam-free, but the spam post is reported to be on 1 relay (Damus). Is this related to the relay mechanism you described the other day?
