Even more occasionally you would find yourself with some 'meta-moderation' points - where it displays some moderation decisions and asks whether you agree/disagree that this was good moderation
The real genius of the system though was the amount of configurability attached to those topics. Each user could define what those categories meant to them, so if you only wanted the serious stuff you could say Funny didn't get a +1 boost when displaying comments, and give it a -1 instead. Or -5 if you really hated Slashdot humour. In the other direction lovers of a good flame war could boost comments flagged as flamebait up in the sorting order. This also extended to relationships, where you could flag people as either friends or foes, allowing you to make sure you always saw comments from people who's comments you enjoyed, and squash anything by people you just didn't like.
All of that was an absolute nightmare for performance I'm sure, which is probably why we don't see it these days, but it was a thing of beauty.
I'd been on the site since before registration and moderation existed, and had a very low UID, back when that ... still really didn't matter.
Kuro5hin's "mean of moderation" system converged (within a five point scale, much like Amazon star ratings), though in practice people vastly overaward high scores.
Explicit scoring systems are difficult to design. They also leak insane amounts of personal information.
