I am not as nice or diplomatic as Faterson... I will just ask you which part of the following you don't understand...
Each user participating at WORLD GOLF TOUR (WGT) may have only one player account. If you wish to create a new player account, please contact us at members@worldgolftour.com. If World Golf Tour determines that you have more than one account, all accounts created subsequent to the first account may be automatically terminated without notice. Continued violation of the Terms & Conditions, including the creation of more than one player account, may result in the termination of all of your player accounts.
For all intents and purposes, WGT has determined that YOU CHEATED.
One account per person.... ONE.
As you have already won credits on this account, I would think that not only are those winnings forfieted, your accounts (all of them) should be deleted and your IP blocked and banned.
But that's just me... like I said, I am not as nice or diplomatic as Faterson et al when it comes to cheaters.
