Well, it really depends on how 'trust' is defined. Is it defined as 'it's a real person (not a bot)', 'a person you can actually trust and with a reputation (meaning: a lot of people know him, personally)' or whatever.

Then the question arises how you want to treat a 'trusted account' compared to an untrusted one.

I think just saying, he's NIP05 verified isn't enough. Because spammers and bots can get verified too.
