Bitcoin Talk account trading seems to be an area that gets most people into trouble with trust ratings. I can't see any reason for doing it, unless you are intending to cheat Bitcoin Talk members, or the forum. Isn't it time we made it a breach of the rules to sell and/or buy accounts?
I'm not if there is any check on this...
but what if someone gives you negative trust without a reason?
Like in this case he has been given negative trust from same user "Lauda" twice?
