Today I read a story of a seller which found himself in the middle of a scam.
Apparently the scammer arranged a purchase of btc and the paying method was a bank transfer. Then the scammer "sold" some good to an innocent victim and requested a payment to the account of the btc seller. The scammer never sent the good to the innocent victim. The btc seller sent the btc to the scammer after receiving the payment. The innocent victim never received the good and wanted his money back ... from the btc seller.
How can a seller protect himself from this situation?
If this involves you at all, or your friend, or had anything to do with this forum; post a thread in the scam accusation subforum and include all correspondence with all parties, TxID's , and any other relevant information. You will get a lot of good hindsight advice from fellow members, and the offending party will likely receive a scammer tag.
