Why do we ban?

[Pepe]

Punishing people was already proven as touchy business. Only temp-banned players are punished ones, as expected effect of punishing is making someone better. So... Temp-banned ones behave nice after return and then just a fact they were banned gives them strong community pressure. It pulls them down to new levels of whatever they were doing bad (also known as ex-convict syndrome). I mean, how many people can really change just to stay in some game?

Perma-ban is not a punishment, but more an example. It's a method of removing ones to make others stay. Not all "others" are nice people, so people we remove are not always evil. That kind of example can be confusing and of low effect.

Talking to people that "can't fit in a box" is most effective, imho. Knowing their needs and then finding them something to do. Is it easy? No. I guess that'd be a reason almost no one is doing it. We are all here to play our game.
