Mastodon PATCH suggestion:
I had an idea for a way to improve and balance between the concerns of both moderation and free-speech. Its a bit radical but I think in theory it could work
Imagine mastodon, or something similar, but where a user can no add hashtags to either their posts or their profile, only the ordinary text of their choosing.
Then hashtags can be added or removed by other users via a consensus mechanism where people can vote for or promote hashtags or suggest their own (not unlike how stackoverflow does it).
Then provide all the tools for users to be able to filter out certain hashtags or promote them in their own feed.
This would allow the community to vote on what is hate speech or what is not, or what is conservative vs liberal, or any other relevant quality to a post or person. Then a user can say things like "Any post that is voted by 70% or more people to be hate speech i want filtered from my feed"..
If done well this could create a system where users are able to completely moderate a system for themselves with minimal effort.
