What is to be surprised here, they are the biggest scam of bitcoin history so far yet so there's nothing to be surprised. They also I heard send back a GPU to some person asking for it (personally I think its a shill account of Hashocean support) but even CLDmine were in charge of more than 700.000 USD and soon after they disappeared and no one knows a thing about them, so there is nothing to be surprised here also. Soon these guys will run away too, maybe they are waiting for that 1 mln dollar thing before leaving with users funds.
