> The current system inevitably advantage those who engage in 100% self-upvote while under the n^2 reward curve those who hold the most SP under 1 account are the one advantaged.

The unfair advantage of n^2 is the same if the SP is in a person’s one or several accounts all voting for the same content.

N^2 failed at highlighting content quality content too. It’s biased to the same group at the top, who aren’t or don’t want to be editors/curators of the trending page.

If you’re looking for ways of achieving better results in token-oriented sorting of content, then consider SMT Oracles (there’s a paper coming out soon and it’s mentioned in my blog) and Communities (see the spec and the Hivemind spec linked in OP).
