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.
It generally isn’t common enough for me to not use it, I tend to prefer it for the shitposts and gaming discussion more than anything. I spend most of my time arguing on Lemmy.ml anyways, so any struggle around the PRC on Hexbear pales in comparison.
