Alot of brilliant comments in this thread. A few of the best:
Perhaps cases could be decided only by the arbitrators who "sign on" to be part of that particular case.
Actually I think that some of those we might imagine to be bad would, if they were elected, get down to work and a lot of imagined trouble might not happen at all.
Serious problem users tend to get shown the door (then the alley outside, then the garbage bins opposite) in reasonably short order. It's the knottier conflicts that are the lengthy and painful ones.
my advice is to work on preventitive medicine, rather than relying on surgery and euthenasia. Or, to be more clear, find a working mediation / rewards for good behaviour system.
