And the solution to how not to catch false positives is to use some common sense. You’re never going to have an aytomated algorithm that can detect every instance of abuse, but even an instance that is not detectable by automatic means can be detectable if someone with sufficient database access takes a look when it is pointed out to them.
Right on. The solution to karma abuse isn’t some sophisticated algorithm. It’s extremely simple database queries, in plain english along the lines of “return list of downvotes by user A, and who was downvoted,” “return downvotes on posts/comments by user B, and who cast the vote,” and “return lists of downvotes by user A on user B.”

And then what will you do with that data? If you find that GrumpyCat666 cast most of the downvotes, does that mean that GrumpyCat666 is a karmassassin, or that GrumpyCat666 is one of the gardeners?
(I can’t find the link now, but early on there was a coded rule to prevent everyone from downvoting more than their total karma. This prevented a user whose name I don’t recall, who had downvoted about some massive fraction of all the comments the site had received, from downvoting any more comments, but this was seen as not helpful for the site, since that person was making the junk less visible.)
