Once, at UC Berkeley, I attended an informational seminar on applying, where one of the admissions ladies got up and proceeded to tell a story about somebody who appealed her rejection five times, each time to a progressively higher authority on campus. IIRC she appealed all the way to the chancellor. When she got rejected, she would just fire off another letter of appeal. Finally they got tired of dealing with her and admitted her. She (the admission lady) closed by saying something like, "If you complain enough, you will eventually get your way here."

To this day that speech baffles me; I have no earthly idea why any self-interested admissions officer would tell that to a room full of prospective students and their parents.

OTOH the advice did turn out to be good; the squeaky wheels definitely get the grease at a large public university.
