How can you win "legit" by not being legit? I think you are missing the point. As soon as you open up several accounts or break the terms in one way or the other you are no longer eligable nor have any right to what might be "yours". You give up the right.
So for example, you have an account there for a long time, then you forgot the log-in credentials and can't recover it in anyway. Then you created another one, and you deposited and won a fair amount, since you broke the "multi-account" thing in the ToS, will that be enough to not let the withdraw go through?
Read below quoted term:
You shall notify us immediately if you become aware that you have more than one Member Account. In the event that you fail to do so, we reserve the right to block or terminate all of your betting accounts.
So it is clear how to avoid being tagged by multi account in case you forget old account and create new account. Simply notify them about it and it will avoid any issues related to multi accounts thing.
The OP said he lives in a dorm with many people and used his own money to win. So basically you saying its ok for FJ to steal his winnings and his "DEPOSITS" too? Is that's what you are saying?
