This is ridiculous. We had shadow banning on reddit in 2007, four years before this was ever filed. In fact, we met with Facebook and told them about it before 2011, and they hadn't considered it before that. I'm pretty sure reddit is where they got the idea...
To be fair, there was no public record of it until 2012 or so.
