A Facebook spokesperson just confirmed algorithmic shadow banning by saying: “There’s a tension here: we work hard to find the right balance between encouraging free expression and promoting a safe and authentic community, and we believe that reducing the distribution of inauthentic content strikes that balance. But just because something is allowed to be on Facebook doesn’t mean it should get distribution. In other words, we allow people to post it as a form of expression, but we’re not going to show it at the top of News Feed."
