If you force users to provide feedback, even if optional, expect many invalid results
In my experience, users won’t go out of their way to leave a worthless review. So if your app doesn’t nag, you have less spam. But that also means you miss a lot of legitimate people who don’t have the time or knowledge to leave good reviews.

> If you force users to provide feedback, even if optional, expect many invalid results
I understand what you mean, but the phrasing of "forcing" someone to optionally do something is odd.
A pop up is forcing users to acknowledge rating the app. It’s not truly optional when you get spammed once a day to submit a rating. So you get angry people submitting unhelpful ratings because they don’t understand the UX
Just to be clear, I was OK with users leaving 1 star if they didn't like it or even better had some constructive feedback. But many were like "great app": 1 star, or "Hi single guy here, and ladies around?": 1 star.
