One of the main features of my site will be Discourse-style trust levels, the higher your trust level, the more moderation privileges you gain. I'm also considering either a jury system, where multiple users collaborate on moderation decisions, or a meta-moderation system, where users can vote "fair" or "unfair" on moderation actions taken.

Someone mentioned to me in another post that Bluesky also has a very good moderation system, but the best one I've found so far is Discourse. What I really like about it is that you earn trust levels by reading posts, not by taking moderation actions. I definitely don't want to gamify moderation the way Stack Overflow did, that was the worst I've ever seen.
