I've been paid back 0.0112 BTC of a total 0.1150 BTC loss. As far as I can remember, there's only been one payment, and it would have been more than a year ago.
So they've started paying back, but very very slowly.

Looks to me like they made one small payment in hopes it would increase volume and when it didn't they just stopped and left the site up with no support or oversight. The real scam is the fake volume that lures people in and from what I read the high withdrawel cost when those ppeople find out they cannot trade.
