A person trying to game the front page could get all kinds of useful info from there. For instance how the flame detector and voting ring detector work and what penalties exist and when they trigger. The ranking algorithm is a lot more than a simple formula.
There was a flame detector (and presumably a voting ring detector) six years ago, but it wasn't revealed by pg showing off that algorithm. Dan could just redact whatever he's not comfortable showing.
