Those people are good at what they do. They have a decent chance of catching something, if there's anything to catch... all it takes is a hint, and they pull the thread. And like you said there are probably other indicators.
Do people get away with it? Yes, likely more than get caught. But the odds of getting caught are greater than minuscule.
Again, I'm talking about majors. At this point most regionals probably want you to pencil-whip your book so they can get you in class faster (they don't care if it bites you in the rear later).
