alex@gleasonator.com@mostr.pub -> look up pubkey at https://mostr.pub/.well-known/nostr.json?name=alex@gleasonator.com

Alex IS associated with both domains, but there is only one NIP-05 identity here. Is there really an issue with having more @ signs? If he wanted to go by `@lex_gle@son@nostr.com` would it be any harder to look up than `alex_gleason@nostr.com`?

Of course I don't care about giving Alex his leet hacker NIP-05. I am wondering how we might proxy NIP-05 identities like Alex did for events with NIP-48. Allowing for @ signs would be unconventional, but seems like the simplest way to do it. Whether it is reasonable is another question.
