it there a policy to restrict an instance to only nip5 verified posters?
might have to wait for outbox support to make that worth it though
nostr:npub1x0r5gflnk2mn6h3c70nvnywpy2j46gzqwg6k7uw6fxswyz0md9qqnhshtn 's Ditto relay policy is hilarious. 😂
Even #fiatjaf is in there

Not yet, just slightly difficult to make it portable because it needs access to your database to look up the kind 0 for each event.
You can hack FLOSS whichever way you want and it's your right to have such a policy.
But it would be a dreadful policy. Please, see: nostr:naddr1qvzqqqr4gupzq5455pmtewaacws6a73hxkqkea6fjwcm3keq9vqu3q7930nl4k9aqy88wumn8ghj7mn0wvhxcmmv9uqpymnfwqcr2ttfwvkkumm594mx2unfvcyv4z98
url leads to a missing note, but primal has the oembed cached as "nip05 is not verification", and it's not, all i ask is self identication, even an unverified display name would help in the sea of npubs
though importing 90k odd kind 0 events has helped somewhat, until ditto can proactively do it for me
