The next gen baker tools ought to have some kind of a "nope" button for entire posts, based on multidimensional text analysis. a cosine similarity would probably work the best. a current post with an identical or high percentage similarity would be flagged as being spam or having been previously noted. the deluxe version would go one level deeper to see if the sauce (URL or graphic) is identical or similar.

According to the tilt of the axis of observation, differing messages could be extracted. Thus Scripture yielded up an infinitude of knowledge that ceaselessly changed. It became a wondrous work of art, beautiful to the eye, and incredible in its pulsations of color. Throughout it red and gold pulsed, with strands of blue.
