That's not how these kinds of "facts" work. If someone tried to use this during some kind of proceeding the court will determine this. (Using a jury or not, expert witnesses or not, doesn't matter.)

Usually fact checking "services" like snopes.com, politifact, or WaPo with the pinocchio heads, have a consistent model about what they are willing to touch, how they approach it, and how they determine factualness, etc.

Just throwing out that Twitter is or isn't _the_ platform makes no sense.
