How big of a problem/pain-point are fake Amazon reviews for you?

Hi HN! I'm a first time founder who's set out on a mission to help eliminate false reviews from Amazon by building a social rating and review platform that connects consumers with trusted influencers. Fake reviews cost Americans 0.12 cents on every dollar they spend, which is 10 cents more than what NASA gets.

I want to know if any of you guys have had problems with fake/paid for reviews on Amazon, so I can be sure that i am solving a problem that needs attention.
