@I-am-Q This is always an interesting topic and I feel it’s in somewhat a grey area. Another variation would be “pressuring” to give a 5 star review, like what I’ve written in my other post before.
I guess the question is will they still give the discount if a user is giving a 3 or below star review. Or do they just give the discount for those giving 5 star reviews. In any case it creates social pressure to give good reviews, even when it’s not deserved.
