The implementation of which was creating a 'Purgatory' forum where there was absolutely no censorship and if people crossed the line too often they were restricted to that forum (though anybody else who wanted to actually engage them could also post). It pissed them off, but in almost all cases, instead of registering new accounts and flooding the main forum with posts (as often happens with banned trolls), they just spout off for a couple days at most, and then either calm down or fuck off of their own accord.
