Have you dealt with eBayers who think they are experts in authenticating? I have a real doozy (sp?) of an eBayer emailing and threatening to discredit me. Here is an excerpt from his email: "Therefore, you either have no idea what it should look like, are lying [which I hate] or have been duped by someone else, whichever, I will report this bag to eBay security, list you with knockoff forums, the purse forum and report you to My Poupette no sales thus preventing any opportunity you may have wanted re accreditation if no explanation is provided. I will also warn the winner buyer to contact a Louis Vuitton store and authenticate the bag..." I have no doubt the bag is authentic, but have had to resort to paying MyPoupette and CarolDiva for their authentication services just to protect myself. What does he mean he will list me with "knockoff forums"? I didn't know that any such thing existed?
