I was trading this morning when I got a pm from someone who knew my real first name ("Hi, Stuart!") I had no contact with this person previously, and have never used my real name with other traders. Even if he had my IP address, that's not enough to discern my real identity (right?), yet he knew it. I'm thinking of bailing on winmx immediately. Would Peerguardian or some other program have made a difference?
