I actually had this happen back in high school. The teacher gave us “anonymous” surveys to gauge her performance. She analyzed the handwriting to determine which one was mine. I actively tried to change my handwriting as well, but I guess not well enough. I’ve never trusted a survey was actually anonymous after that.

In college once I took a course that was being offered for the first time. They gave a midterm survey (usually we only had final surveys). I filled it out honestly, saying that my partner for our group projects was not pulling his weight. I had forgotten that I was in the only group of two (all the other groups were of three). The professor actually pulled me aside to let me know that he was aware our group wasn't working out - unfortunately there wasn't anything he could do.
