Amazon does what's in their own best interest. This year, it looks like scamming is it.

I wrote a 1 star review last month on a scam product (I fell for) with obviously fake reviews (the product was an earplug, the 3000 5-star reviews was totally generic or for womens beauty creams). The review was rejected because it was violating Amazons "policy". The scam product itself and the 3000 fake reviews was fine.
