Trolls get banned and we know they're going to come back, the second/third/hundredth time around they usually manage to stay around a little longer, but what do they get out of it? The internet is communication, communication runs a wide gamut of variety from friendly flirting to full on war, but they don't get that range of communication, all they get is the sense of being disliked, probably paranoia and because they're inflammatory a lot of people won't even answer them seriously on the occasions they do try to make a post that will 'fit in'. I'm against banning for all but the most serious cases (when someone has purposely tried to hurt someone specifically for instance) for a number of reasons 1 - I believe people have the right to voice their opinions. 2 - We know they're only going to come back and they'll try to disguise who they are and lay low for a while, it's a waste of our time banning them as we then have to work out who they are again. 3 - Often if you don't ban someone they go on to become a normal member, they make connections with people, invest time in the site and cool down to normality. But what do the members who join and rejoin and troll from the start get out of it, and why do they do it?
