I think that's an incredibly dangerous game. I remember things a few years ago that were considered "fake news" and "conspiracy" theory, that have been more or less proven, or are at least an accepted mainstream view. Shutting down debate and banning accounts is not a way to encourage any kind of reasonable discourse. I see it as a pu**y way out of a debate, if the information is wrong, that should be pretty easy to prove, if it's not so easy to prove, it's at least worth discussing.
Who gets to be the fact checker, and how does that person know what's true or not? What's considered a fact or fake news? What if Will (or anyone) posts a video with incorrect technical information? It's not true, and can be proven untrue, so is he now spreading fake information and worthy of an account ban? It sounds ridiculous, but if you put a blanket ban on "false" information, that would be included.
