Redietz, have you ever walked up to the sports betting window to place a bet and been told, we don't want YOUR action? Have you ever been denied entry into one of these contests because of who you were (a known sports bettor)?

You have never mentioned anything like that, so at the risk of assuming, I will assume not. But once that happens I think you will view the value of protecting your name including anonymity on forums and message boards a little differently.
