There are portals that connect reviewer shills with sellers who want to boost their product ranking. Google "buy amazon reviews" and you'll see it. Some do it individually, on fiverr for example. The portals themselves are a very lucrative business, and are not going away anytime soon. There is an arms race between sellers to get that sweet sweet real estate (get their products on page 1 or page 2), and business can be a cutthroat matter. Of course, the system will eventually come to a steady state when too many buyers get burned buying crap. Review and feedback systems is a topic I'm very interested in.
