I imagine a forum for politics with the same rules of enforcement would have one mod constantly on there banning topics after 10-20 posts as we are not able to handle politics very well.
With those types of topics it takes on bad egg to ruin the bunch. I personally don't want to see it because I don't care what others think about what Obama or whatever should do in blah blah blah scenario. Here there is none of that and it is peaceful-ish.
Quick look made it seem like 15 or so of the same people. Seems like half of them are like here and the other half use quite a bit of distasteful humor and word choice.
