I'm a bit biased. I had a professor who informed his classes, after the drop deadline, that < 85% on any test meant an F for the semester. I had no opportunity to cheat. All but a few students failed. It was $hundreds wasted for me. He was demoted to a non-teaching position when everyone complained. In this case Harvard may go overboard on a crackdown, to shore up their reputation that's worth a lot of money to them. In that case the students may need to counter with a lawsuit, to restore fairness. > what counts as "unfairly" gaining an advantage? Ultimately it's best for you to decide, as fallible as your judgement may be. Anyone else may have their interests at heart, over yours. Their pet interests may be enshrined in the rules, the law, and/or the public psyche.
