Briefly explain the trade: He was offering diablo 3 keys. I told him i would like as many as he had. He said he would sell four for $100. I sent the paypal, and he stopped responding.
How they scammed: He did not follow through delivering the keys after paypal was sent

Here's all of the chat window that it shows, is there a way i can get it to show the entire conversation in that window? Clicking the link at the top just brings me to the chat log

 

Not that I know of, I'll be closing this. If you manage to get the full chat, post a new report.
