1) Stop writing weirdly formatted walls of text and use the proper format for reporting scams:
[b][color=black]What happened:: [/color][/b]
[b][color=black]Scammers Profile Link: [/color][/b]
[b][color=black]Reference Link: [/color][/b]
[b][color=black]Amount Scammed: [/color][/b]
[b][color=black]Payment Method: [/color][/b]
[b][color=black]Proof of Payment: [/color][/b]
[b][color=black]PM/Chat Logs: [/color][/b]
[b][color=black]Additional Notes: [/color][/b]
2) If he told you up front that they were carded, and you implicitly or explicitly agreed to this before buying them, then you agreed to the risk that came with said cards. Therefore, there is no scam here.
Selling carded cards deserves a negative rating though.
