And I suppose that you have positive proof of that allegation?
e-Bay is nothing more than an online location for vendors to sell items. Your local newspaper does the same thing. Neither of them are obligated to investigate whether items posted for sale are stolen or legitimate.
e-Bay works very hard to remove listings that are fraudulent every single day. In the final analysis, the onus is on the buyer to make sure what he is buying is on the up and up, not e-Bay or Craigslist or any other publication. Your post is ludicrous.
