And before someone comes and says that I want to police free speech, no. Not at all. I simply want curation which means a set of processes that are followed for certain categories of speech, and the labeling of potential speech as incorrect or untrue. I don't want to lock anybody up for posting fake news (though wouldn't mind if they were banned)

You're doing a fine job right here. But Twitter seems to be a far better option than Facebook for that kind of scenario.

Average Joe has a facebook account with a network of friends. They do not have a twitter account let alone any followers (Facebook DAU: 1.5 billion; Twitter DAU: 126 million)

Fair point, looking at Facebook as a platform and product I think it has far greater impact than Twitter.
