But if there is an official CNN Mastodon instance, it’s suddenly real easy to see if someone claiming to be a CNN reporter is real or not.
Are they @john.smith@cnn.news? If not they’re a fake.
It would also work for official Microsoft accounts or Colgate-Palmolive or the government.
Seems like a good idea to me. And if you like federation it sounds better than a semi-official instance everyone uses that verifies things, sort of recreating a mini-Twitter “super” instance that is “more equal” than the others.
