OP, how can you so sure about he bet on another sportsbook?? Do you have a rat in other sportsbooks? IMO OP's claim is weird, this "void issue" will keep me away from this site. Although the site margin is low, I afraid losing money here because they may confiscate or void my winnings. 
There is no need for a "rat" on other sportsbooks
Actually, detecting arbitrage betting is rather easy for an operator as there are pretty clear and simple indicators. You could actually google about it and its detection.Not only voiding my bets. They banned me permanently and kept all my money in the account. God knows how they define their terms and execute on us.
Actually, we only voided your winnings obtained from arbitrage betting which resulted in a negative balance on your account. As mentioned before, this is due to the fact that you withdrew such winnings before we detected and stopped your arbitrage activity.
