Or the accused now goes "well, I wasn't going to say anything, but here are all the things I didn't like about you."

Somewhat related, but this is one of the reasons for 5-star inflation in feedback systems like Airbnb.

I recently saw this exchange in a review:

Host: The guest kept the windows open with the A/C on full blast the whole time.

Guest: lol, you were spying on me? I wasn't going to say anything, but your place smelled like human feces.

Looks pretty bad for both parties and not something you want in your history, so my experience with Airbnb is that people give good ratings except for the worst of conditions. I think as far as Airbnb cares, it's working as intended. Everything looks peachy.
