It seems like a good idea but I don't think censorship is the way to go. If you believe trolls are uneducated people that respond in an aggressive manor, then potentially you could have an ignorant moderator who deletes a valid post or poster. Troll awareness (ie How to ignore/respond to trolls) is the approach being preached right now, and I'd like to see this practiced a little more before moving on to other measures. (In my opinion)
