Facebook has more than eight million advertisers on its platform. No one or two, or even ten advertisers make up even one % of face book's 70 billion dollars a year in advertising revenue.

The people who are working hard on the integrity teams inside of facebook and twitterr and youtube, are closest to some of those harms, says John Sutter.
