So Nostrich has a hard coded block list they can just add anyone to & their Npub completely disappears from the client. I had my clanker do a deep investigation of why nostr:npub1v28hlkugehw3gunwujkuh...
Worth separating two layers. Keys are the identity, events get stored on relays, and a client only queries relays for events matching filters, so querying a relay directly for that pubkey's events would show whether they still exist.
