This seems rampant in mobile app reviews, too. Using the Health Equity app made me pissed enough to go look at the app reviews in the Google Play store. Shocking - if you look at all the people that give it 5 star, glowing (canned) reviews? Who did they work for? Just take a look for their names on LinkedIn and it’ll be real obvious what was happening.
Not a 1:1 comparison, but your thread immediately reminded me of it.
