Dear Twitter ex-pats. When we all flounced out of Twitter loudly proclaiming we were going to Mastodon this sent a message to trolls, nazis that they could set up servers & come here.

If anyone gets harrassed with hatespeech pls note that that is not the culture of Mastodon. Please report & block those users. If you notice a pattern from the same weird domain, block that domain, write a post of the server name w/ a hashtag fediblock so your server admin can follow up & block it for everyone.

@caffeneko Question. Can users block entire servers on Mastodon? If that's possible, then the trolls can be isolated. And it would make a great story
@DanaBlankenhorn @caffeneko yes, I believe you can, at least from the web browser. This problem isn’t new with the Twitter exodus. Mastodon had entire Nazi/fascist servers a few years ago. They may still be around but everyone else has blocked them.

@DanaBlankenhorn @caffeneko

I just checked. You can do it if you're logged in through a web browser. Not sure how to do it on the official app (or if it is even possible).

@rmacanthony @caffeneko I was really wondering whether since it's federated, trolls could be isolated from decent people by servers blocking any servers which host them.
@DanaBlankenhorn @caffeneko Yes, that's exactly what has been done in the past. Those servers can be completely isolated from the rest of the fediverse.
