The brilliance of reddit was "anyone can create a reddit that they run for any topic" so the "community" was handed to the people and the site managed infrastructure.

In the time-honored tradition of virtualization, I would propose simply to have "moderator" subscriptions similar to subreddit subscriptions. At face value the site is unmoderated (modulo necessary legal requirements), a user may moderate as they please, have AI moderator filters, and share these publicly at their choice, and subscribe to moderations others have shared.

The whole free speech issue began when sites decided that they ought to know what people should and should not be listening to and reading. Easily fixed though, keep the speech free, it's free to the person who speaks, and let the listener and reader choose on their own what they shall and shall not listen to.
