People were asking recently why anybody would want to ruin an academic with false allegations and suggested that this only happens in my field. Well, I just read a story of one Prof. Theodore Piepenbrock in The Times that I recommend people Google for a British example of this phenomenon.
By the way, I have seen the behavior like this TA’s a quadrizillion times. Some professors (the ones who suffer from anorgasmy) feel flattered and cave. Some resist. But they are hunted relentlessly in direct proportion to how much they make and how many connections they have. The practice is not gender-exclusive. As we see from the linked piece, nowadays those who cave and those who don’t can be punished in the exact same way.
