My answer to this question was deleted by Borror0:
I think that most answers will need to be referenced. I have only posted one answer so far that was not referenced. This answer pointed out flaws in other people's logic and pointed out the difficulties with figuring out how difficult the situation is. Ideally I would have referenced this, but these aren't easy ideas to find references for. My argument was too long to post as a comment and I didn't want to allow incorrect ideas to stand unchallenged and so I posted an unreferenced answer.
I think the most important test is whether the answer helps bring us towards the solution - or really just wastes our time.
I don't believe that this was an appropriate use of the moderator power. If there are any issues with this answer, they could have been resolved either by a comment or by making an edit.
