i feel like a dick saying it, but that was pretty much well deserved
forums are forums, they're an implementation of free speech.. if you're not expecting something like this when you try to control them in every which way, then you probably shouldnt have a forum
i dont feel bad for them, if they didnt want to handle all that, then they should just shut them down, or remove all the bans and let people just talk (aka tribalwar)
but they'll probably just shut them down
oh, and reporting someone to an ISP for spamming forums is pretty damn low
