This already exists. If people include their website or Github URL in their profile, and they have their Mastodon account listed on their website, it will automatically verify them.

I think what turns me off from Mastodon is that it's mostly a monoculture. If you say something that doesn't agree with the dominant politics of the Mastodon community, you are going to have problems.

I am politically-moderate (from a US viewpoint), but any instance that is remotely right-wing is blacklisted on the several Mastodon instances I've checked, effectively shunning them from the Fediverse. I personally enjoy reading stuff that challenges my beliefs.

Another thing that keeps me from Mastodon, is that when I do occasionally checked my rather curated list, it's still just a bunch of complaining. Complaining about Elon, Twitter, about political events, etc.

Ironically, and despite Elon's best efforts at destroying Twitter, I find it much more diverse and useful. Much of the whining has disappeared and, for the most part, I'm getting better content. That said, I question how much longer Twitter will exist and/or be relevant.
