The original agreement was his Runescape accounts for a Steam accounts, with a link to three free games as well as a CD-Key which I bought later that day to Counter Strike. The condition was that we wait 14 days and then I give him the CD key, so he wouldn't recover back.
Actual query logs from IRC will show me linking him to an image that reveals the username and password of the steam account I made him, and him saying directly after: "the accounts are yours."
At this point, the trade had been mostely done, and I started doing what I needed to to sell the Runescape accounts.
Soon after, Bambino_91 tells me he wants his account back because he got a better offer. I tell him that he's have to buy the accounts from me at the resonable price of $50USD.
After denying to pay for the accounts, he reovered them.
As far as I'm concerned, this is scamming because he took back something that he had already traded away.
I did not take back the steam account that I made him, and I'm left with a CD key that cost me about $14.
I can provide IRC and MSN logs of him giving me all teh account information, including the recovery questions, passwords, email information, dates of creation, etc.
