I don't know the details of this case other than what was posted here, nor do I have any experience with this member. So I don't want to make any accusations toward this member, or this sale.
However. Possibly for this, and more importantly, for anyone with similar situation on any format with any sale (forums, ebay, craigslist, etc). False sales are a federal crime. It is mail fraud, and there are federal agencies there to protect you. Specifically the IC3 (Internet Crime Complaint Center found at
www.IC3.gov) will take the complaint, investigate the claim, and file appropriate charges for internet/mail fraud. Mail fraud is any scam that claims to be selling an item that will be shipped/mailed to you, and then either does not send it, or sends something that is not what was advertised. The IC3 is very effective, and I have first hand experience with them. People don't realized there are federal laws against stuff like this, and even if they do, they don't usually know how to take any action. I'm trying to spread the word, to hopefully cut down on internet scams.
