As I suspected this is plagiarized. Again you don't seem to have that 6th sense that should be telling you something isn't right about these pieces. I have told you this before, but you really need to start looking at the blog of an author and taking into account their whole output when you are trying to decide if an article is the work of the author. Of the last 3 articles this author has written , including this one, one was flagged down below $0 payout, and another was noted to be plagiarism by a reader in the comments who left a link to the article that mustayani had "rewritten" (read, changed a few words around to make it less likely the plagiarism would be detected). But even without looking at the past history I was pretty sure this was plagiarized - you just don't see an article with this many facts and this well written that doesn't cite ANY sources... unless it is plagiarized.
