Slightly off topic, but when I noticed that there was sort of a market for prior exams for the CS courses I was teaching, I made it my policy to provide students with all prior exams. I'd have preferred that no-one had them (easier on me), but given how much an advantage having a prior exam is, I can't find it justifiable to favor those with the social connections that gave them access to such exams, over those who didn't-people with friends, people who belong to fraternities and sororities, etc. etc. etc.
