I don’t think people need to enshrine anonymity absolutely to post crap daily for millions of followers. You could have an accreddited human poster who proves not only humanity, but also agrees to a few rules to maintain this credential. And then you could still have non-accredited posters who nobody vouched for, but everyone should instantly doubt and dismiss their big claims as shitposting.

This would also have to be state-provided, because states and citizens are the ones who lose the most with infowarfare, corporations don’t care.
