This would be a good time for a third party website to allow reviews of buyers and sellers. You could also integrate product reviews with it. Amazon reviews have gone to shit since everyone knows how to game the system. You could then differentiate between the ebay seller and the product ebay was selling. Make it work with amazon, ebay, newegg, sears, walmart, and other large third party seller websites. Could eventually add in functionality like camelcamelcamel for price history. Then burner accounts across multiple sites could all be associated to one master account.
