You know the answer better than I do Alex. ActivityPub and Nostr are different beasts. There’s still plenty of spam on ActivityPub, but historically, if someone uses a Mastodon, Rebased, or whatever server to mass-register bots and spam the network, the server under attack will be defederated faster than you can say "moderation."

I’m not saying that Mastodon is failsafe, by the way. There are plenty of unpatched vulnerabilities being exploited. Luckily, "ReplyGuy" doesn’t have thr hots ActivityPub at the moment.

Still, my point stands: NIP-05 verification only requires someone to post a nostr.json somewhere. The equivalent Mastodon "link verification" feature isn’t what’s stopping Mastodon servers from getting hammered.
