It's worse than a Turing test: it's trying to distinguish between a honest human (writing content they are knowledgeable about or that is original) vs a dishonest human (who writes filler content just to get a higher ranking). It would almost need to be able to read the author's mind to figure out their intention. Or, given a text, figure out if what it is saying is original and/or true.
