There was a discussion this morning in a reddit sub where I'm subscribed called /r/watchpeopledie. Sounds pretty crass just from the name, and a decent percentage of regular users wouldn't be bothered to look much further. Some of the people subscribed there are concerned that the this is exactly the logic that will follow - they've banned a sub for disliking the obese but not a sub where people watch murders and executions and talk about them (and let's be honest - sometimes make jokes)? The sad thing is, it would really be a shame to lose that sub. It's one of the few I've found where community policing works actually works, there's rarely disrespect (and what exists is almost always downvoted to oblivion), the moderators are just as involved as the regular users - most people there seem to be on the same page.

The consensus seems to be that these "fringe" subs are safe as long as they refrain from brigading. I guess we'll find out. And who knows? As a moderator of /r/serialkillers, maybe my opinion on what's appropriate is skewed.
