I would like to highlight this quote from the admin lemm.ee from their similar discussion on hexbear:
Let me play the devil’s advocate here and employ some “self-whataboutism”: among all users that have been banned on lemm.ee for bigotry, the majority were actually not users from other instances, and in fact people with lemm.ee accounts. If we judge any larger instance only by bigoted posts that some of its users make, then we might as well declare all instances as cesspools and close down Lemmy completely. I believe it’s far more useful to judge instances based on moderation in response to such content. Just as we remove bigoted content from lemm.ee, I have also witnessed bigoted content being removed from hexbear.
