Cyber safety: Avoid putting phone number on Facebook
 

Beware! If you put your phone number on your Facebook profile, anybody can then find your details and location by just typing the number in Facebook search bar despite your privacy settings -- and your details could be misused by cyber criminals. Reza Moaiandin, technical director of Salt.agency, used a coding script to generate every possible number combination in Britain, US and Canada, Daily Mail reported. He then sent millions of numbers to Facebook's app-building programme (API) in bulk. In return, he received millions of unobstructed personal profiles.
