My question has no answers, only a comment.
The button seems completely unresponsive and does not delete it. I remember that a while ago I was able to delete all my questions.
For example, I have a question which got hit by downvotes and was put on hold.
When it closed I had -3 votes. Today I had -5 and that made me lose all of my rep.
This also seems stupid. If the question was closed, what's the point of keeping the votes working?
