Most folks can spot a fake review a mile off .... it does open up opportunities for better methods of verification by sites, however, not even the biggest sites can get the density of bona fide genuine content going across all products and subjects. People are just not interested in providing wholesale contributions, and in other cases they simply don't exist for many review subjects. At best it's an 80/20 rule , leaving the majority exposed to very poor content.
This content model is flawed and a very poor quality signal in a lot of high profile cases IMO.
