Congress interrogated Facebook founder and CEO Mark Zuckerberg for two days this week over his company’s privacy policies—and its apparent inability to prevent the misuse of its social media platform by some promoting hatred, terrorism or political propaganda. Throughout Zuckerberg’s apologies for not doing more to protect users’ privacy and curb the spread of false and misleading information on the site, he repeatedly reassured lawmakers artificial intelligence would soon fix many of Facebook’s problems. Zuckerberg touted several AI successes before two Senate committees: Judiciary and Commerce, Science and Transportation and the House Committee on Energy and Commerce. Facebook AI algorithms already find and delete 99 percent of terrorist propaganda and recruitment efforts posted by Islamic State in Iraq and Syria (ISIS) and al Qaeda-related Facebook accounts, Zuckerberg testified during Tuesday’s Senate hearing. But the Counter Extremism Project (CEP), a nonprofit nongovernmental organization that monitors and reports on the terrorist-group activities, disputed Facebook’s claim the same day. The CEP issued a statement saying it still finds ‘examples of extremist content and hate speech on Facebook on a regular basis.’”
