Anonymous feedback (like really anonymous) is the answer. people can't give real feedback and be nice at the same time.

I think feedback fatigue is a real thing though. The comment about only leaving feedback once hit home to me. It's rare I bother reviewing something twice even if asked, and especially if my original round of feedback didn't seem to change anything (which I understand is totally reasonable in many cases, but still a little disappointing).
