I've been keeping a similar list for private use, only mine is much smaller - less than 30 questions now that I removed the more risky ones which I never asked like "Is any of the board members actively addicted to anything?".
There is no scenario in which they would a) know the answer confidently enough they'd tell an interviewing prospective employee about it; b) be willing to do so; and, c) be stupid enough to do so.
I wouldn't have a clue. Short or knowing them socially, how would I know? Given they're 4 levels above me in the org (me->VP->SVP->CTO->BOD), I have zero reason to interact with them on any basis, let alone a social one.
