Amazon Review Services

Hello guys! Was into Amazon about a year ago and I remember that buying reviews was fairly easy (a lot of offers on Fiverr and a lot of services were found in Google). I know about Amazon's crackdown on fake reviews, but what is the current situation? Is there still any services out there?
The thing is now I have an ability to make 10-100+ daily reviews of HQ but I simply can't find any other offers on that topic to study the market. Would someone be interested in that?
