I'm not sure if I'm right here, but my guess is that the reason a lot of people who were banned from WP went back and trolled the site was for a little bit of revenge. They thought they were treated unfairly to begin with (and some may not have given a shit anyway) so decided to make the mods actually do their job and clean up the site. Trouble is, with the changeover a couple of years ago, the now incumbents go too much power given to them and came down hard on anyone who broke the slightest rule. Shit, there were some members who got into good arguments that got banned, for merely going against the 'protected species'. I thought a forum was there for everyone to be able to have their say, and to get answered back in return. There didn't have to be flame-wars, but arguing points of view is human nature. Stopping the natural process and stacking the decks hinders what the idea of the thing is about. But then again, we are talking about WP here.
