I don't think you should call him scammer until he actually scammed someone.
You can call him suspicious but you have no evidence ATM.
With my signature advertising I'm betting on him being earnest because I have nothing to lose and much to win.
Only time will tell.
You promoting this site is helping him scam, you really want to do that for the lousy pay?
Absolutely not. I'm helping in testing if this is scam or not.
There are no proofs atm.
Signature advertising is one important test.
In few days we will know.
EDIT 26/12/2003: Ok, now we have the proof this is a scam
