I recently came across this question. At first glance it just seems to be nonsense, but then I realized that it actually had had genuine mathematical content before the op edited it. In the comments to an answer they write "Can you delete your answer please? Because I want to use the concept to somewhere else confidential. Please understand me".
Beyond the issue of this specific question I wonder if there is some kind of community consensus on the appropriate reaction in such a case?
Should one just downvote the question for its low quality? Should one revert the op's edits? Or flag for moderator attention?
