First, you're a douche.

As for punishments, perhaps when your kids do something wrong you punch them in the face? Because that's what this is here. Nothing wrong actually was done to anyone, it's entirely a theoretical issue, and you went right to the nuclear option. Short of banning, slay and purge is just about the worst thing you can do to someone. You went from 0 to 10, which is both stupid and calculated to piss people off. You could have just slain. Or you could have said next time you'll get slay and purge. You could have done a lot of things. But you didn't.

Because, you know, you're a douche.
