It is the opinion of many posters that as long as people visit the site, it doesn't matter how abusive, threatening or distasteful peoples post are - no action is taken.
Trouble is you think right that's it, I am not going to visit this place anymore due to the type of post you mention, but after a while cold turkey sets in and I get mornings like this when I have a load of housework to do, but anything seems more interesting than cleaning the sink.
Good luck with your protest.
