The problem was that registered users WERE the ones posting the nasty anonymous posts (for the most part), it wasn't just random anons who happened to come upon the site for one day, clearly the anon's who were posting new the history of things on both sides of every disagreement.
Sometimes when I want to ask a question, I wish I could go anon. but the thing is, what have I really got to hide? Nothing. NO sense in being embarassed about anything. I know it's easier said than done but that's just how I feel.
