That’s the problem. If there was a well-known user named “foobar@lemmy.world” and the instance went down, that would be a perfect opportunity for some other random person to create an account named “foobar@sh.itjust.works” and claim to be the alt account of “foobar@lemmy.world”, just on a different instance because lemmy.world is down at the moment.
Pay attention to the domain lol
Same shit with spam emails

Fair, some sort of verifiable identity marker, people hate crypto but an nft in your wallet could be used for identification.
