Re-used a password to an email account he attached to MTGox on the web shop of a person he had reason to believe engaged in questionable activities which might include financial crimes. Within hours of personally investigating his own email account, gets this person to agree to give back what remains of the funds stolen if this is all kept on the down low from LEOs. Hmmmmm.
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.
