I have located a suspect, his name is 陈建海(Chen Jianhai). He's NOT my friend and we have never met in person. He was one of my previous business associates because he's very familiar with credit card fraud and he advised me a lot (in terms of fraud prevention, of course) when I built my virtual goods payment processor in late 2010.
He has knowledge of my secret gmail address and I have once re-used the password in his web shop
His English is not very proficient and I'm sure that he's not reading this forum at the moment. I'm giving him a call now to persuade him to admit his wrong-doing and return the funds.
I'll post another thread soon.
I was one of the first to predict that zhoutong had taken the money in an inside job.
I'm now going to predict that he'll discover his "acquaintance" took the money and it will be returned shortly.

And I predict there will still be people that think he is innocent in all this...
