I asked a question a while ago on Super User: https://serverfault.com/questions/227152/what-is-a-good-os-to-mess-around-with-xen-dom0
I logged into Super User today to find it had been moved. I don't see anything server-specific about the question however. And what is more troubling is that I can not even see who closed the question because the original question on Super User has been deleted (which I didn't think was possible, and I definitely don't think is a good idea).
So why was my question moved, and more worrying, why was the original question deleted?
