Stay tuned. On the Facebook piece try Jillian York/EFF fantastic piece about how "Getting Banned From Facebook Can Have Devastating Consequences."
I believe that this problem stems from a lack of diversity at Facebook. Seventy-three percent of Facebook’s US leadership is white. Globally, 77% of the company’s leadership are men. Women make up just 32% of the company’s global staff, and only 2% of the US staff is black, a number far disproportionate to the actual black American population.
