Let's say I asked a bad question and the question have been closed, but the voting is still open. Now someone answered my question resulting that I am unable to delete it. So every now and then someone see my question and vote it down because it is bad. So yes, I learned my lesson and desperately want to get that out of my life because I get -rep the whole time.
Is there a feature to close voting or when a question is voted closed to also close voting?
