I don't know. At the first glance it would make sense for downvotes to be treated like upvotes (as you suggest in your previous post, I was only contending the "winner takes all" part), at least to some extent, and I don't see any issues with that, but it doesn't mean there must be none. I only spoke up about what I was pretty sure to be fundamentally flawed. By no means I claim to have a perfect (or even demonstrably good) solution for the problem.

By the way, "winner takes all" was how League of Legends (MOBA game) Tribunal system worked - reported players were judged by the community in a punish / don't punish vote, "judges" were rewarded if they cast a vote that eventually won. Even though you could not see how the voting went so far, wondering how people would vote was still a big part of the decision instead of the actual offences commited by the player. The system was later retracted (and replaced by other means of dishing out common punishments, which are arguably worse, but that's another story).
