Basically because the laws in this area, due to first amendment rights are very clear. If you put out an article like they did on S/A look for two points. One he is declaring he's short and secondly look for the word opinion. As long as you say that you can pretty much say anything. Unfortunately this is how it is.

The articles themselves are not relevant they are used by Hedge funds and groups of traders to initiate short positions (attack) in this case and use the articles as cover. Motley Fool does the same thing. The sites don't care because they know that the law suits won't stick and they drive traffic to their sites which is really what they want...
