For good reason we don’t accept people yelling “fire” in a movie theater. Anti-vax misinformation during a pandemic is definitely in the same vein as yelling fire in a theater.

There are a few solutions. Don’t know that any of these are possible, but sometimes solutions only get found in a listing of possible solutions.

Any sourcing of the internet as a source of truth could be called into question on face.

Or massive platforms could find a way to be less massive. Ie “we’re just not going to host governmental agencies or politicians.” Also bracketing the scope of posts and information on social media.

Or who knows.

Edit-one observation I’ve had is the internet is best when tied with another source of truth. Ie you can generally try recipes from a website and tell whether it makes palatable food by just making and tasting it.
