In my opinion, that IS an ambiguous question. Not in the sense that it's hard to understand approximately what you're looking for, but that it's not obvious how to choose the right answers. I agree that this kind of moderation can be a bit heavy-handed, but I think one of the goals of SO is to have provably correct solutions to questions, not an "answer wiki" like Quora. You can't really "accept the right answer" to this question in any fair way.
