Last week Facebook CEO Mark Zuckerberg gave more than 10 hours of testimony before Congress. During questioning before the House Energy and Commerce Committee, Rep. Eliot Engel (D-NY) asked Zuckerberg about hate groups scraping data from users.

“We do not allow hate groups on Facebook,” Zuckerberg replied. “If there’s a group that their primary purpose ...is spreading hate, we will ban them from the platform.” That Friday, Facebook kicked prominent white nationalist Richard Spencer off its platform.
