The whole "no anti-impersonation is good, Twitter added verification for #brands" things is naive. That may have been birdsite's motivation, but the feature had other uses.

Impersonation isn't just shitposting Mr. Clean, it's fake Anita Sarkeesians screaming racial slurs as actual libel. The ability to prove which you is you is an anti-abuse feature. We need to implement it the Open way instead of sitting around all "MY privileged ass doesn't need this, so it's needless."
