Criminals are finding new ways to utilize Facebook to commit new and disturbing crimes that authorities dont necessarily know how to police. Cyberbullying is a common occurrence among teenagers on Facebook and can result in serious criminal charges if it goes far enough.

Be careful what you say on Facebook; you may be committing a crime without even knowing it.”]
