I have no doubt that grade grubbing is a long and honorable tradition among students. However, my perception is that the style of grade grubbing changed over my years as a student, grad student, and then professor. Grade grubbing used to be attempted through some combination off ass-kissing, attempts to obtain sympathy, and polite persuasion. Towards the end of my teaching it was more frequently the kind of rude and outraged sense of entitlement displayed in the links. Aside from any other considerations, I was always shocked that some students thought that the best way to get a better grade was, well, to be an asshole to the person responsible for giving that grade.
