There are reports of spam coming from specific users on lemmy.blahaj.zone. I stumbled across some very unpleasant NSFL content on an unrelated post. I wouldn’t reccomend it, but you could check [email protected]’s profile for an example if it hasn’t been taken down yet.
It may be worth temporarily blocking that instance until they get a handle on the situation.
How many people who individually block will go back to unblock?
I individually blocked the spam account. Didn’t come by more than one. But getting people to block and defederate seems to be the motive here.
Probably none, which is why it’s likely better for the instance to be proactive with doing it and work with the admins of the other instance in monitoring.
