Why would he decide to post ''nour''
Maybe he gives some clues who he is?
Nur (also spelled Noor, Nor, or Nour, Arabic: نور: Nūr IPA: [nuːr]) is a common Arabic unisex name meaning light. An-Nur, meaning "the light" in Arabic.
That is a lot of examination. I do not think that this post has any such meaning and is probably a case of hacked account only.
