The right model would perform some kind of flow analysis, starting from the vote graph. I guess there must be standard techniques in web search (linking as voting) and the like, that oppose spam linking (page rank? I haven’t studied what it is).
You are looking for “attack resistant trust metrics”. Google’s PageRank is one such; Raph Levien’s Advogato algorithm is another; my TrustFlow is a third.
I’ve wondered if it wouldn’t be better to give relatively more weight to votes from people with high karma. I haven’t proposed it because it seems counter-productive to escaping the dangers of an echo-chamber, and because it seems like a conflict of interest coming from someone with high karma.
The rule should be stateless: users vote, and it’s data. Then, there’s an algorithm that computes karma of users and rating of comments, starting from that data. Giving more weight to high-Karma users (adjusted for inadequate voting=significantly different from what others value, and for balance of votes) is similar to electing moderators, and ultimately roots in the founders’ conception of what’s on-topic, what’s valued on this particular forum.
