How handy is that now I can easily find a friends phone number. FB only has or shares information that YOU supply them with. It only publishes things that YOU have given it permission to tell. Your friends have chosen to Share that information with their friends. How is that a violation? How is that scary? If you don't want 'your stuff' shown don't share it. By the way everything you post or share on QB can be searched for and found on GOOGLE.COM. If you are all concerned that someone you don't know may read or see your stuff you should probably get off the internet altogether.
