Facebook on Thursday banned conspiracy theorist and InfoWars founder Alex Jones and the accounts of other controversial figures. The company, citing violations of its policies on hate speech and promoting violence, is also blocking religious leader Louis Farrakhan, who is known for sharing anti-Semitic views; Paul Nehlen, a white nationalist who ran for Congress in 2018; far-right figures Milo Yiannopoulos and Laura Loomer; and conspiracy theorist Paul Joseph Watson. Those individuals and accounts that represent them are also banned from photo-sharing app Instagram, which Facebook owns. They have rules, but enforcement is completely random," said Roger McNamee, a high-profile Silicon Valley investor who has become a sharp critic of Facebook. "They don't do anything about it until massive harm has been done and they can no longer find a dodge. Facebook is clearly feeling pressure." McNamee said Facebook's business model depends on amplifying content that stimulates fear and outrage, and banning a few influential figures doesn't change that. "It is sacrificing a handful of the most visible extreme voices in order to protect a much larger number of users it needs to maximize profits," he said. The Menlo Park, Calif., company didn't say what specific posts or actions led to the bans, though a spokesperson said that Jones, Yiannopoulos and Loomer have all recently promoted Gavin McInnes, founder of the violence-prone far-right group the Proud Boys, whom Facebook banned in October.
