Using Your Authentic Identity: How Facebook's real name requirement creates a safer environment.
People connect on Facebook using their authentic identities. When people stand behind their opinions and actions with their authentic name and reputation, our community is more accountable. If we discover that you have multiple personal profiles, we may ask you to close the additional profiles. We also remove any profiles that impersonate other people.
If you want to create a presence on Facebook for your pet, organization, favorite movie, games character, or another purpose, please create a Page instead of a Facebook Profile. Pages can help you conduct business, reach out to fans, or promote a cause you care about.
