Amazon should come up with a proprietary and secret algorithm (the way Google search is) to do the same thing. They are in the best position to do this, since they have all the info. They could leverage purchase history, payment methods, addresses, account age, etc...; they even have the resources to use slightly more invasive information such as credit score. It's knowable what products are having fake reviews bought for them, they could secretly flag accounts suspected of this and lower their weight. Fakespot can't get half of the information Amazon already has. Amazon needs to fix this for themselves.
