Still, what MTGOX did is far from lawful/good/just. You see, on mtgox.com page, there are no terms of service, no anti-scam policy, nothing. When users register, they do not agree to anything ! So mtgox had no damn right to do anythyng, *INCLUDING* any freezing funds !
Too bad, because in my country mtgox would have to go to prison for up to three years if he didn't lock the funds. Aiding trade of stolen goods is illegal in most places. In my country the law will not normally be included in the terms of service either. It is obvious.
Time to look for another exchange i guess ?
Good luck with that. If the exchange declines to follow the law in the country where it is located, your money and coins may disappear very quickly when the owner goes to jail.
