I have been seeing two scenarios that you may want additional close or flag options for. Admittedly, they do not come up too often, so this may be a general question with no action. I am cool with that.
Here are the two scenarios:
The OP has a questionable motive: The OP sometimes seems to be a bad actor looking for information on how to carry out unsavory practices. There are times where the request is legitimate but needs clarification. Other times, it may be a question that if answered opens up a liability for the site.
The OP has a legal question: The OP sometimes is looking for legal advice and this is not a legal site and any answer would be an unprofessional answer. I have answered copyright questions and can competently comment as an amateur, however asking for legal advice generally means that the OP is about to step into something that could get them into real trouble for which the proper answer would be seek legal advice. Again a potential liability.
Just a couple of thoughts. It may be that some of the current close or flag options are good enough or could be modified or new ones added to cover this. I leave it up to the masses and the Mods.
