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 soot@lemmy.blahaj.zone’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.
It’ll be unblock once their mods deal with the account.
They need to deal with the methods these accounts use, not just individual accounts.
How many people who individually block will go back to unblock?
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.
