Sandbagging is cheating. You're artificially lowering your score so you can win money from players whose real skill level belongs in the Hack, Amateur and later Pro tiers. It's exactly this kind of behaviour WGT needs to take more seriously and deal with. And right now you should be in the cross-eye.
Besides, you have two active accounts, which is not allowed according to WGT's rules. You're posting with this one and playing with the other, and have access to both, have created both. That is not allowed. Do you seriously think WGT will just sit idle by? There are enough people with multiple accounts already. They don't need you showing them your *** in broad daylight and getting away with it.
It's a silly thing to begin with. You're clearly good enough to do well in tournaments, so why turn to cheating to win even more money? You have all the clubs and balls you can dream of anyway, I'm sure, so is it just a contest to earn most money on the site now? Is that what riles you?
