I was always suspicious of Fakespot's ratings and had very little ways to properly A/B test. I would see products on Amazon - both with 4.5 stars - but one would have a Fakespot score of 1 star and the other would be 4 stars.

After that Honey expose I started to wonder if Fakespot was simply trying to steal the last click referrer and using its "we filter fake reviews" as a cover/lure to get people to use it.
