Yes. But those instances are a) young, which the lemmygrad userbase isn’t, and b) not run by the lemmygrad admins.

Also, not at all all instances are open to be a source of posts that tankies would like to make. Both lemmy.ml and lemm.ee have a rule saying “no bigotry”, how that’s interpreted is a completely different thing with people getting banned from lemmy.ml for “orientalism”. Not in the “Marx was eurocentric” sense but “you’re not Chinese so you can’t criticise China” one.
