At some point Cormen had a page of shame where he would name people who asked him for solutions to some of the problems. I remember it was removed with a note that it was a bit much. Though, I suspect it was pointed out to him that this made him look bad.
I think this says a lot about the logic of the authors, though.
i frequently see him post on Quora--he appears as a pompous, abrasive and highly anti-social individual who acts like a gatekeeper to knowledge. He grudges the readers their knowledge by making it extremely boring and difficult to break into. Many 'authors' are like that. Which is feels like a conspiracy.
