The changes include banning convicted sex offenders from the site, limiting older users' ability to search online for subscribers under 18 and building a task force seeking ways to better verify users' ages and identities.
Facebook has more than 70 million active users worldwide.
Among other changes, Facebook has agreed to:
• Ensure companies offering services on its site comply with its safety and privacy guidelines.
• Keep tobacco and alcohol ads from users too young to purchase those products.
• Remove groups whose comments or images suggest they involve incest, pedophilia, bullying or other inappropriate content.
• Send warning messages when a child is in danger of giving personal information to an adult.
• Review users' profiles when they ask to change their age, ensuring the update is legitimate and not intended to let adults masquerade as children.
