What I do (and it is just me) is to try to determine how plausible or relevant the question is to life or a life situation. Some questions might be an analogy to a given problem and the OP uses it as to not air dirty laundry, theirs or others, in open forum. If their responses to their own post seems more quip or joking and not truly serious in any attempt to gain any clarity I would suppose that would be closest to a question that is pulling one’s leg. There is no other way to say it, so I will, too few questions seem to be on a serious nature, I don’t take more than maybe 8–12% to actually be ”question” questions, so if they are not serious hardly comes to thought.
