Who said I was an Itachi fanboy? you sound hurt kiddo. I searched for this genjutsu statement and can't find it. In fact there isn't even a source for it on the wikia, and according to another who tried to use this claim on another site.. the statement predates the introduction of Tsukuyomi to begin with. So whether it is true or not(which you need to provide an actual source) Tsukuyomi and other high calibre genjutsu were introduced after the fact.
