From time to time, I run across questions like this one. When I do, I usually vote to close (as I did here), but actually that does not seem sufficient to me.
I thought about whether it made sense to rollback the last edit to at least restore the question that was asked? Or maybe just leave a comment noting that you can delete your own questions? Or maybe flag it as very low quality? Or maybe just do what I did and wait till the question is deleted some time in the future?
Since I ran across some of these already, there probably is some consensus on how to deal with these.
