OK, so after being hit with dozens and dozens of fraudent orders in the past few months (totaling over $10,000 US) I've got what appears to be the real IP of the bastard (or atleast one of them).

I installed this script to deny orders from proxies and it seems as if in the particular step of the order which this is checked for, he momentarily turned off his proxy to bypass the script and his real IP address was recorded! It's from a dial-up ppp connection from an Indonesian ISP.

This guy has been playing headgames with me for months now and I'm out to fry him!!

What's the first step here? Should I contact his ISP and inform them of this? Who's the indonesian authority responsible for cyber crime? Any guidance would be appreciated!!!

Honestly, though I have never delt with this(contacting someone with athority about a matter like this). I think your best option would just be to email the isp with logs and what the person has done and hope for the account to be cancled. You ever read the long story on grc.com about him trying to stop a dosser, I mean this guy had it located down to the town where the kid was located and still couldnt get anything done to him(mainly due to the isp in my opinion) and the kid was in the US. So email the ISP and hope for the best.

contacting his ISP would be a good idea... explain the entire situation to them.. and ask them for his contact details.. try contacting him.. if that doesnt, give the good o'ld FBI a call...
