Blocking.
Instead of bans, Twitter could just add people to their own block list, and then tell new and existing users that they can opt-in to a moderated Twitter experience. They could have different block lists for different moderation reasons. E.g. Bots, spam, vs terms violations.
An even better solution is a delegative blocking system for accounts and keywords. It's basically crowd-sourcing account blocking, where you are saying: "I want to block all accounts and keywords that this person blocks". Then you can have an allowlist to override some blocks.
Don't like conspiracy theorists? I am certain there are many people willing to tag all the conspiracy theorists they find.
The best part would be having a toggle that can show you all the content that is blocked, and why it was blocked (i.e. You delegated all your blocking to account X, and they delegated their blocking to account Y, and account Y placed this account on their block list named Z).
You could also have "smart block lists" where you could use queries to block people. E.g. "Block all followers of X". An issue you might have though is to differentiate between those that follow in support of someone, or follow simply to know what they said and challenge it.
Twitter used to have block lists but they got rid of the feature. See: https://help.twitter.com/en/using-twitter/advanced-twitter-b...
Ideally I would like this for all internet content.
So I agree with Jack when he says:
> The biggest mistake I made was continuing to invest in building tools for us to manage the public conversation, versus building tools for the people using Twitter to easily manage it for themselves
Just as long as its always opt-in for everyone individually.
