Beehaw, one of the largest lemmy instances, announces that it will be defederating from lemmy.world and sh.itjust.works.
we have made the decision to defederate from lemmy.world and sh.itjust.works. we recognize this is hugely inconvenient for a wide variety of reasons, but we think this is a decision we need to take immediately. the remainder of the post details our thoughts and decision-making on why this is necessary.
In short, they are defederating from these instances because they have fully open registration, without applications or manual approval. As a result of this, it has been exceptionally difficult to moderate content originating from the users of these instances. Beehaw hopes to federate with these instances again, once better moderation tools are available for use with lemmy.

I wonder if there's some other reason. Yes, Lemmy.world is public and people can register freely... But I'm yet to find a single troll or outright abusive account, and I basically follow /new all day long.
So as far as I can see, the "moderators are getting overloaded with trolls from Lemmy.world!" isn't true. Could be in the future, but not now, really.
It's hard to imagine tbh. I haven't seen a single troll. I've seen all of one person get a little temper going but nothing outright malicious or offensive. Ngl, I'd be interested to see some examples of said trolls. Not denying it, just super curious as to what qualifies as trolling in this case.
