<p>As soon as someone provides an answer, comment, edit, or vote, the question has become the work of the community.  Poorly posed questions--non-questions--should be closed as such, and usually will be (by high-rep community members and/or moderators).  There's a gray area, such as the incorrect formulation you refer to, but in general any well-posed question that has generated non-trivial community interaction ought not to be closed without public discussion.</p>
