I've been censored far more on Lemmy.world, and never on Lemmy.ml. I got permabanned from Political Memes on Lemmy.world for asking why the mods were removing comments pointing out the Democrats involvement in the genocide of Palestinians, and was tempbanned from Lemmy.world's asklemmy comm for calling out transphobia.

Lemmy.ml is one of the better servers with respect to "censorship," it doesn't defederate from the Leftist instances and it removes bigotry pretty much instantly.
