I think that’s an awesome idea and I like that it proactively gets ahead of the problem instead of the retroactive approach like moderation today. I’m interested in a very similar goal; I’ve been working on a guide on anti patterns in internet discourses at https://odap.konaraddi.com in hopes of it being used to make discourse on the internet more productive and pleasant (the guide is a work in progress).
Thankyou -- and wow that looks an amazing site. We desperately need more pleasant discourse (I think HN in general is a great example of good discourse, by and large) and I feel like you've codified some excellent rules.
