A side question for folks who work on these sorts of social media / UGC sites. Wouldn't a shadowban / deletion of messages be a lot less antagonistic as a way of dealing with problematic posts instead of instant and total account ban? I mean, if Reddit can shadowban so that your account still works, even if the posts go into the "ether", why can't Twitter do this? Instaban seems a bit... harsh, even if merited? Couldn't you combine shadowban with account ban if there's a persistent set of violation posts? Is there a practical reason why shadowbanning on twitter doesn't work?

I mean if we're going to use fairly simple approaches (keywords on ban lists or user-based flagging / reporting), then shouldn't step one simply be not allowing the post at all, instead of a retroactive instaban on the account after the post has been shared? To me, the simple way is delete the post, or put in a hold queue (warning the user), or at very least not actually share the post on a timeline. Warn the user, don't share the post, and/or delete the post. Then you can still have the desired effect of keeping the platform "safe". Am I missing something? I'm confused all around about social media practices, honestly.
