zhoutong may be thief or not, but those (AurumExchange) who fingered/accused zhoutong as thief, so far NOT done/doing anything legally & just watching how forum members get angry, shouting, scolding zhoutong.
The main issue is that this had been brought publicly on this very forum before by Zhou Tong himself, complaining his funds were stuck with AurumXchange.
In that kind of case, the only thing a company can do is to release a statement explaining what happened.
I hope calling some one thief publicly & doing nothing to prove that he is thief in legal way, is not applicable in any country.
