This is not about people leaving 1-star reviews. This is about people leaving 1-star reviews for lunatic reasons. I once saw one on a hiking app, saying the path was not flat and there were no stairs. I mean sure, that is information that might help you ; but what the hell do you expect from a mountain trail with >500m of elevation difference in a natural reserve. Sure that's not the craziest thing out there, but it baffled me.
