Just came across a deleted answer used as a review queue audit. I can't find a way to link back to it, but it was an answer by superuser.com/users/590578/estela-duarte on this question: superuser.com/questions/196977/…. The wording of the answer was a bit spammy, and it was a single post by a brand new user to a very old question. What likely tipped the scales was that the link was broken.
