I'm not arguing for consuming misinfo. I block for harassment. And yes, misinfo can lead to real harm.
But the way we best figure out what's true is dialogue and sharing good journalism/science. Not admins being referee. What I fear they will usually do is take the current consensus position, with a bias towards their user base. Alternative but sometimes correct views will struggle to find a place they can be posted that is well federated to go viral and correct misunderstanding.
