Sometimes a question is posted that widely disliked (often due to being too easy, or being excessively arbitrary, or playing around in a space that's been mostly comprehensively covered without actually being a duplicate). These tend to get downvoted heavily quickly.
However, they also tend to get closed, often with reasons that don't really fit. (Even more commonly, the challenge initially is closeable, but then reviewers refuse to reopen it after the reasons for which it was closed are fixed.) Should we be closing this sort of challenge? If so, what reason should we use? (At the moment it's typically either "unclear", or "duplicate" with a duplicate that doesn't fit.) Should we then be deleting the challenge after it's closed? Alternatively, should we leave the question open, but highly downvoted?
(I don't have any particular question in mind here; I've been meaning to post it for a while, and am asking about the general case. This one, however, is what reminded me to post this, and will serve as an example for the sort of question I'm talking about. I'm not at all sure my close vote there was correct; originally I misread the question, made the close vote, realised my mistake, equivocated on retracting it, made a comment explaining the issues I found with the question, then found that the close was completed by other people. I'm fairly confident now that a reopen vote on the question would fail, and I'm not at all certain I did the right thing in the first place, but I'm also not sure I can do anything to correct it.)
