Probably thinking I was too stupid to follow up, I began the manhunt. He used a lot of very similar aliases on Reddit, and the identical email around the internet tied to publicly displayed IP addresses while scamming others. Tracerouting those IPs all zeroed in on the same exact town. He also foolishly used a real mailing address(his friends). The images he posted showed the serial number of the card I had on file. During this time, he continued to berate and taunt me from all of his aliases, even asking me tech support questions on how to fix the undervolting mod I had done to the card. I remained silent.
My favorite quote. "being a scammer dosen't make someone a bad person, it just makes them smart for being able to outwit other people into handing over free money. Thanks for all your help I really appreciate it. Fuck you, and have a nice day. Next time you shouldn't throw your money around like it's a boomerang causes it's not gonna come flying back to you every time something dosen't go your way. i know my morals and taking money from people who have nothing better to do with it than throw it around like it's nothing on the internet dosen't seem like a crime to me."
At this point I was ready to board a plane and confront this punk.
Instead I compiled all of the information I could find on this dude, and created a 20 page document of evidence. That's when I contacted the police in his local hometown. It was met with a luke warm response, so I contacted the local news station and explained everything to a reporter. A day or so went by and I was contacted by a local officer that was friends of the reporter.
Fast forward a few days, the officer had visited the homes of both this kid, and his friend. The kid emails me crying, WHY DID YOU SEND THE COPS, why would you do this to me? Shortly after that I begin getting emails from his 'father', on how it's my fault that I didn't verify his age, and I'm forcing his child without permission to trade money for a video card, and contributing to video game addiction. How it's not their responsibility to pay for people selling "stuffs to child" without parent's knowing. "Are you still trying to finish trade with children?". On and on. So I press full charges with the police.
End of the story, Mom gets involved, apologizes, and sends me the full amount in Paypal + shipping and fees. Best part is I actually got WAY more than the value of the card, because I had set the original MSRP as a starting point. Done.
I wish you guys could read the entire email saga, and all of my documentation. But hopefully that's enough to get the gist :)
