Why are some flags declined when the question is being closed anyway? Is there a set of rules to decide if each flag was helpful when closing? Since the flag drew attention to a question that needed to be closed, isn't it helpful regardless of the type (excepting, of course, spam and offensive flags)?
I ask because I flagged this question as general reference, since the user could have looked in any dictionary and found the answer (that one of the words is not a verb). The flag was declined, and the question was closed as "not a real question."
