Probably. I have no experience with the Google Play Store end of things, but we’ve gotten non-reviews written by crackpots removed from our Google Business profile by just pointing out to Google that they were either off topic or from someone who we could not identify in any of our records as being a person who actually did business with us.
For example, there was one guy who went around copy-pasting the same one star rant to seemingly every retail business in the city whining about mask requirements during COVID, which didn’t have jack monkey squat do to with us and was in fact a state government mandate that we did not control. As a public business we have to comply with the law. Google took that one down when we reported it, although I still see examples of the same screed from the same guy attached to other businesses who apparently didn’t have the wherewithal to complain.
I imagine “app that serves third party content the author doesn’t control and reviewer is complaining about the content not the app” is a situation that is very well understood at Google. Whether or not you can make them give a shit is a different question…
That’s not the point. When you respond to reviews like this the goal is to point out to everyone else who might be reading it that the reviewer is in fact a nut, and therefore their opinion should be discarded out of hand.
