I'd like to pose a question. Let's say you searched any one of the major search engines like Google, and along with your results, you saw one of the paid advertisements in the results. You clicked through the advertisement and later conducted a transaction with that business that was advertised on Google. The transaction later goes south and you lose your money. What level of responsibility should Google have in this situation? What if you saw the ad on TV instead....should the TV station have any responsibility to the purchaser? What about radio, newspaper, road-side billboard, or any of the other countless mediums in which advertisements appear?
Why should NSXPrime be any different than any other medium in which advertisements appear? In my opinion it shouldn't. That said, I'd like to see a Buyers & Sellers feedback section added to Prime for both Private Sellers & Vendors. It is always up to the buyer to do their own due diligence, and the Feedback section would be a useful tool to enable them to do so.
