Overly moderated message boards. Obviously that's not the case here, but other message boards are terrible in that regard. For some, it's just a ban on controversial topics. The moderators can become very strict about what constitutes controversial (they wouldn't allow a discussion on SOPA even though if passed, it could have killed the site), but compared to some of these other sites, bans on controversial topics are at the low end of overly moderated. I've been on message boards where mods have banned people for things as petty as spelling and grammar errors. And then there's the editors. My god the editors who have to edit every post so that it fits perfectly in line with everything else. Fucking font can result in editing and don't get me started on those douchebag mods who delete or edit posts because they go slightly off topic.
