Not really because ukyo claimed some time that he can do withdraws manually. This stopped then though. So this withdraw might be from a time when the manual withdraws still were possible.

Of course you are in a special situation. The coins you deposited belonged to you and ukyo only had them in escrow. Its a shares wallet of course but normally those coins would be attached to you and werent owned be weexchange. So at a possible court case you might claim that he gave your coins to others to solve weexchange debts. Strictly spoken coins that were deposited and users bought shares with it wouldnt belong to them anymore. But coins that werent used to buy anything would still belong to someone.
Of course that only would help you as long as there is a chance to get the coins back.
