Okay, so for some context .ml is run by the Lemmy devs and the devs are openly tankies (authoritarian communists). .ml, along with Lemmygrad (also run by the devs) and Hexbear are known as the Tankie Triad. While not as bad as the other two, .ml still has a lot of tankies compared to instances that aren’t part of the triad. Additionally, .ml used to be the recommended instance (until .world came along), making it one of the more populated instances. Most other instances defederate with Lemmygrad and Hexbear, but not necessarily .ml.

Basically, there’s a lot of extremely opinionated and often combative people there and provoking them (intentionally or not) is very easy.

That’s my understanding of the situation anyway.
