I know there's a great deal of discussion about how to deal with this. I want to point out something I see as quite positive, Mastodon's abuse tools are really good. The ability to isolate nazis into their own echo chambers is a much more potent form of control than people give it credit for. It's not perfect, but being able to block them at the instance level is streets ahead of birdsite, and resets the entire situation in everyone else's favour.
