Why is it passive-aggressive? I see people here talking as if it was the responsibility of the community to engage with and resolve the problems of challenging and unproductive members. How many hours in the day are there? Why is it our expectation that everyone is owed attention, forbearance, and even satisfaction? These aren't social services we're talking about. There's no "due process" clause.
Is the problem that the community isn't telling the problem person that they're banned? There's a reason they don't: because by and large, when you tell someone they've been banned, they react (particularly in the heat of the moment) by throwing a temper tantrum with a new account. Again: why is it the obligation of the community to absorb that kind of abuse?
