I meant the none-public downvotes will lead to abusive behaviours, maybe different abusive behaviours as we see now happening. Public visible upvotes is not driving abusive behaviour, not as far as I can rationalise this.

Abusive fighting: What if we would get some governance bodies in place with a more-or-less decentralised structure, with the ability to hide or downvote a post to zero without the need to collect the enormous amount of SP? ie some kinda of super user accounts with high SP? The way these bodies are created needs careful design to make sure these bodies in itself will not become abusive.
