rottenfruits seems to be banned, and jackshephard seems to be using the same thread. It looks like a clear case of ban evasion to me. Mind telling me or providing me with proof of the user scamming? I may have missed something here.
You should always thread carefully with people who are self-moderating and selling these goods. I find it acceptable with some senior members with known trade history, but definitely not with fresh ones (such as the case with rottenfruits).
He has most likely scammed in the past, however, the biggest offense this user is committing is selling gift cards that are obtained through fraudulent means. In this case it seems he is most likely using stolen credit cards to purchase them.
Take a look at his threads. $200 gift cards for $80. He claims to be getting them from refunds ..nice even 50, 100, 200 amounts...haha
