I often wonder whether "limited downvotes" scheme would work: (let's say) 30 downvotes per 24h are free to use and after that each downvote decreases your karma by 1.
My personal opinion is that downvotes, upvotes and algorithms are design decisions that often stick before the best one is found.
It's a shame really, because I think it's not only really important (e.g. to combat fake news/users etc.) but most interesting.
Nonetheless, HN did good with their version where the max. downvote of a comment is -4 and where the up/downvote of a comment is not listed publicly. All functions that help with community building. However, I fret the moment when AI users and shills take over (especially since throwaway accounts are so easy to create).
According to https://github.com/minimaxir/hacker-news-undocumented "After users reach 501 Karma, they gain the ability to downvote another comment."
