Made me sad reading this. I've avoided this by making sure everyone knows you never increase grades, unless there's a grading error. Also, in spite of putting more nicely worded instructions than the ones in the article, I always have around 2% of students completely miss them. More instructions have not decreased that for me. So why do more of them?

At one point I said to a student - "You should really work as hard at learning as you do trying to negotiate a higher grade!" I assume they rated me low, but I stopped reading those things years ago.
