I do not understand what you are talking about.
I do not know who Plaz, Megaguy, or Ephi are, and I can guarantee to you that I am not any of these three individuals.
Plaz is some guy who got banned a while ago and has made several alternative accounts, which he made an intelligent sounding 'Hello, Forums' or 'Hi I am ____' topic. He usually is discovered because he insults people on the forums as those accounts which a new person should not know, and Ephiatles and Badspot (Moderators) cross check the Ip addresses. Hes just like a disguised virus of the forums, who keeps getting expelled and comes back in as a new form. A classic example would be the 'I am Pinto' topic. Oh, and if you try to do a crime in secret, the forums will interrogate the hell out of you.
