Several reasons - We don’t have the time to justify on an individual basis why we reviewed a flag one way or another, and I don’t believe there needs to be that justification, because we trust our admins and moderators to make these calls.
Secondly, it would cloud opinion of some people and in some cases that might be unjustified. I saw a user recently with a very low score, who isn’t a notable name here, and in that example, I simply determined that they aren’t really sure of how the flagging system works, rather than it being malicious. If that was public data, we’d all write that person off as a bad actor, or as weaponising flags when that might not be the case.
And finally, the role of moderation here is up to the admins and moderators, and it’s difficult enough in many cases without there being an open debate on any individual person’s score.
