@kbsez @Rwsavory @digby That's the only control we've got. All we can do is not pay attention to crap. It does not stop the crap. And I'm okay with that. Especially if they don't realize their crap is being ignored.
Every instance is responsible for the traffic it generates. Or rather their responsible for their users. If their users a problem, you kick them off, if they don't kick them off, you kick off the instance. It works very well
