Rewarding players to rate your App is highly effective, specially if your players are invested in your game and your reward delivers meaning. A while a go I had my App PewDiePug with 40’000 Active users permanently banned because of rewarding them to leave a rating. After removing the behaviour on my other Apps and iOS Versions, Apple featured an app doing exactly so.
What is the official statement from Apple’s site?
Does Apple official accept this?
