This question popped up at least twice in my review list and I struggled to provide a response I would feel comfortable with and this was not the only review that puzzled me lately.
The question is not "closable" or "flagable". It is possibly only "downvotable" but this will not stop it from appearing as an unanswered question (of which there are more than one thousand as it seems).
Is there already a guideline about handling this type of questions? Would it be useful to be flagging them for mods to put them "on hold" until the OP improves them? Can a question be put "on-hold" for a reason beyond the ones provided by the "close" functionality? Would it be useful to have at least 2 mods review such a decision in case it could be perceived as preferential and unfair?
