Was it because someone didn't want the post to be seen? Unknown at this time.

I regret to say that this is scare-mongering of the same type that Fox "news" uses, as in: "It is as yet unknown whether there are any links between the bridge bombers and the Occupy movement."* If you don't know, don't suggest -- it just plays into the paranoia. Which of course is what Fox wants, but I don't think you do.
