1: First it's your shopmate, now it's your cousin, weird exchange but ok. Your cousin or 'shopmate' traded the wrong item. Once the other person found out he contacted your cousin to trade it back as it was a misunderstanding (that's what you called it in the ticket, you claimed your cousin didn't know about it). We gave your cousin time to trade it back. Your cousin ended up telling the scammed person to wait, and then took off instead which makes it a scam.
2: The same IP was used for several PHP offenses, hence why the ban will not be lifted either way.
Lastly, after answering several of your tickets, I asked you not to create any more topics/tickets regarding this issue. The ban won't be lifted. PHP is a serious offense and a permanent ban is it's punishment. Please refrain from making any more topics regarding this issue.
