Buying Positive or Negative Reviews: The final rule prohibits businesses from providing compensation or other incentives conditioned on the writing of consumer reviews expressing a particular sentiment, either positive or negative. It clarifies that the conditional nature of the offer of compensation or incentive may be expressly or implicitly conveyed.
Amazon has had this rule in place for a long time and I still get cards in the boxes of the stuff I buy, "Give us a 5 star review and get 30% off your next purchase!"
Clearly Amazon doesn't know about this or isn't generally enforcing it. I'm wondering how the FTC is going to patrol this since Amazon has already had this rule in place for a while and it hasn't dissuaded sellers from changing their habits.
(as pointed out, it is also illegal for AWS to do that)
Given that hundreds of people reading this thread have experienced exactly what you’re talking about, I think it’s impossible that Amazon doesn’t know anything about it.
Not one has ever conditioned it on expressing a certain sentiment, rating, or anything at all.
But I think most people feel strongly enough they should leave a positive review in exchange for money. It doesn't even need to be said.
