Common knowledge doesn't mean that people are unsubscribing at the rate people are joining, though. I'm not saying they need to hire moderators (I believe it is ultimately up to the community to effectively enforce the rules), but if that continues to be the gateway through which everyone enters, the problem will continue to grow. Responsibility could simply be offering a means after registration to find subs relative to your interest, rather than dumping everyone in the same, tainted pit and expecting them to do the legwork to get out of it.
