I agree as well. Anything that falsely raises reviews should be banned. It’s a common greasy scheme used by lots of companies.
“If you give us a five star rating, at the end of week you get put in a drawing for a free iPad. Only seven people in so far, so it’s high chances.” Overheard that at an auto repair shop I went to that was the highest rated in my city. All their prices were much higher than anywhere else. While waiting for help several people came in complaining about the terrible job the mechanics did.
Anecdotal story but an example. It’s fraud with extra steps.
