Facebook is one of the most popular social media sites with over 1 billion users due to its free and easy-to-use platform for communicating with friends and family. However, it also faces criticisms around privacy, child safety, cyberbullying, and hate speech. In particular, online privacy has been a major issue as some users would post important personal details that could be stolen. Facebook has taken steps to enhance security features and restrict certain details, but still receives complaints. Child safety is also a concern as underage users can create accounts without parental permission and be targeted, though Facebook has increased protections. Cyberbullying, especially among teens, and hate speech are additional issues Facebook addresses through monitoring and enforcement actions.
