I don’t have the ability to easily verify users. A user verification service would be great. I think it could work decentralized, but maybe have a separate service for it. Servers independently authenticate, and federate with each other. If one starts authenticating poorly, defederate.

I don’t think it’s a good fit within Lemmy or Mastodon, or … Because I don’t think someone who runs a server wants to bother with it. It needs to be it’s own service that integrates with other services.
