There is none, or at least no more than any other site. In fact, Twitter moderation is leagues better than old forum style moderation (dang is an exception :)). I waited for years post-2016 to see any real evidence of the “fake” news that is demonstrably false and has somehow infiltrated the world and… there is none. People just don’t like the ideological spin of the headlines and moderation decisions which, I mean, what’s new?

My advice is don’t hold your breath. This is exactly what you think it is.
