HFS. I am glad I got my coins out of there a long time ago. This is horrible news and I hope they are able to recover the funds lost...
I think they took the money and ran with it. Only logical explanation for the way they are acting and handling the situation. The less said the less they will have to explain later on.
Alternate story: you could be right and this could be Cryptsy 2.0... follow the blockchain transactions for the wallets for Cryptopia and see where the coins went....
