I don't see why they don't just run people plain 'outta town just like back in them good ol' days.
Seriously though, why can't we just ban people from a town for being arseholes. Send them to a place where their loud behaviour and barely comprehensible garbage is tolerable. I don't know where, but maybe if we group all these people together they'll sort themselves out. Maybe kill each other. Their economy couldn't possibly survive, there's only so many drug dealers and jobless 21 year olds that one community can support.
