How can social media platforms respect users’ freedom of expression while also protecting them from harm? With more than 3 billion people active on social media, it’s a challenge of unprecedented scale in human history. Over 400 hours of video are uploaded to YouTube every minute; Facebook removes around 8 million pieces of content per quarter for violating standards for hate speech, bullying, and terrorist propaganda; Twitter takes action against around 250,000 unique accounts each quarter for violating hateful conduct rules. Are social media platforms fighting a losing battle against the sheer volume of content? Companies are ramping up content moderation efforts, but they face major questions about how to create content standards, how to balance global rules with local context, and what the role of each stakeholder should be. Investigate some of the ways companies can solve these challenges in a way that balances security, privacy, and freedom of expression.
