Not surprising at all at this point. At Fakespot we've noticed a huge surge in fake reviews that originate from Facebook groups where sellers and professional reviewers meet.
The way it works is that a seller provides some kind of incentive (gift card, paypal money, etc) to write a 5 star or even 1 star review (for competitors). Facebook has hosted these groups and they have exploded in numbers in the last year.
