This ties into something that's been discussed a fair bit, here and there.
When an editor, quite rightly in my opinion, disallows a question like that, he is often told, by an irate author, that he is highhanded, working from personal preference rather than rules, "dumbing down" the quiz, and interfering with the author's vision.
Very often, I find, that kind of question is used as the last question in the quiz, as a "sting" of some sort. My standard line, when editing, is "We find it's not a good idea to irritate and annoy your players just before they get a chance to rate your quiz."
