Facebook appears to be “shadow banning” the non-profit education site PragerU, founded by talk-host Dennis Prager, causing a drop in engagement of 99.9999 percent while outright removing two videos regarded as “hate speech.”

PragerU, which produces educational videos on conservative issues, has 3 million followers on Facebook, but almost none of its audience saw recent posts.

A screenshot of the dashboard for PragerU’s Facebook page shows the last nine posts have reached between one and three followers while previous posts have reached between 50,000 and 95,000.
