This question already has an answer here:
Recently I have asked the question on how many Atilla the Hun has killed. I showed research and question is plain and simple. Atilla the Hun is considered to be in Top most vicious people, however I could not find any data on how much he approximately killed which makes it hard to compare him to others. User Samuel Russell came over said that he didn't know the answer (and there is none) and then closed the question.
Do you think that "We don't know the answer" is it something you consider an appropriate reason to close a question?
