Just got scammed by these utter scumbags.
They let you create more than 1 account on the IP (say, if youre in a shared, frat house, live with friends or family who like to gamble that YOU recommend the site to initially). SO they let you deposit, THEN tell you 'oh you cant get the bonus because another account was created on that ip.'. They then DONT LET YOU withdraw your deposit until you've wagered it all away.

Bunch of dishonest scumbags who rely on dishonesty and misdirection to gain money.

Stay away from these guys. Their support team are a bunch of tools as well.
