This post makes me think of SL4:

The most active place on the internet for discussing Friendly AI is the SL4 email list. Ironically, it must be one of the most hostile email lists on the internet with frequent flame wars and people being banned from the list. The moderation system consists of so-called “list snipers” whose job it is to ban discussions that they don’t like. If these people are experts in friendliness… lord help us.
