Its nice to have a website where you can monitor thousands of websites and quickly get an understanding of the company you are looking to buy from. It do agree with your email that kicking off the "fake" reviews is a great idea, but I feel that Facebook is not the right channel for this. It may be an idea to wait until someone has posted more than one or two reviews before they are published. Most of the "fake" reviewers only ever make one post.
