Hi there,
Did you ever tried contacting all those link exchange sites about his rip off? They will deleted his link, as well, post a warning about that site. That's what I did when some website claims all that kind of shit. It's one way to strike back, quietly....
Also, how did you give your 500$? Check? Cash? Credit card? Credit card is way easy, since you can call them that you have been charge by a frauder and the credit card company will look into it.. Check and cash, good luck. Those are hard to track down. You can also contact Western Union as well, since they do the credit card processing for that site.
Also, you can contact those sites he says he helped and see his claims. If his claims are falses, tell those webmasters that their good site have been used by a frauder! It's all here, TopCash.com, etc...

You can also contact the police or someone who deals with online fraud. If those codes are actually belongs to him, well, it's pretty, if they aren't, he will be in deep shit.
Well, that's all I can help with. Let me know if you need help with all this.
