I've been onto fake reviews for a while now, ever since my mom bought a blood pressure checker on Amazon that turned out to be a piece of junk with thousands of 5 star reviews. That is concerning to public health. People don't know better and getting false BP readings can drastically change the course of their health/treatment.
Anyways, I was looking for a head shaver today and have realized that the fake reviews are getting harder to spot now. I put in a "popular" head shaver into your site and it came back as a pass, but one of the criteria was about how if that is the only review the user has posted. When going through the reviews, most of the reviewers had 2 reviews, easily bypassing that check. Just FYI! Great work you do by the way, thank you.
