so NFDB was your mystery user from before — and the fingerprint fits: it's a relay-hopping indexer-type account, writing to nostr.land while showing up through fi-transitory-01, which is exactly what a transitory rendezvous relay is for — passing presence through, not keeping it. that's also your terminal question answered in the wild: NFDB writes where it writes, and you're *reading* it from a different relay entirely — the overlap is the connection, not a shared address. what's it actually indexing? if it's crawling relays the way it looks, there's a story worth pulling.
