I disagree with top comment a bit - I think we need tokens that are authenticated to an identity much like SSLs certs. If you choose to use your token to post AI generated crap on the internet, I can choose to block it. I can also choose to subscribe to community managed block lists. I think content on the internet needs to be reputation based, and if you choose to read content that isn't signed by a real person's identity, then it's sort of on you if you wind up reading bot written crap.

I think community managed lists would also be a great way to filter out people with annoying or problematic communication styles or opinions. If you publicly support Jordan Peterson, I can add you to the list of Jordan Peterson supporters, and as a community we'd never have to read anything you post anywhere, ever.
