Don't Fall for Fake Reviews: I-Team Uncovers Them on Yelp, Facebook, Google

Yelp told the I-Team that as many as 25 percent of reviews submitted to the website are fake

If you rely on online reviews to pick restaurants, businesses and services, beware: the reviewers you're depending on may be fake.

Follow-Up: Yelp, Facebook, Google Remove Fake Reviews

The NBC4 I-Team uncovered hundreds of apparently fraudulent reviews for Southern California businesses, and online experts warn there could be millions more. The suspicious reviews appear on Google, Facebook and Yelp, and praise the services provided by restaurants, dentists, doctors and home remodelers, among many others.

Beverly Hills dentist Dr. Rodney Raanan told the I-Team he could not explain the source of what appear to be dozens of online fake reviews for his practice on Google and Facebook.

"Interesting," he said, when told about Google "reviewers" whose online profiles feature allegedly made-up names paired with photos of actors, actresses and other well-known personalities.
