I’m aware of some stuff like that some instances have defederated from others for anti-communism (lemmy.world / hexbear.net), but that’s where my knowledge ends.
I’m looking to understand what instances to be aware of, each instances’ political leaning, defederation etc.
Even their website mentions that Lemmy devs are “controversial” just because they are Marxists. And to add to that, their users are fucking loud about using piefed.
