Facebook used to be interesting.
You could secretly spy on your school crush and look at photographs of their husband to see if you were better looking than him….(I wasn’t).
You could spy on the school bully who flushed your head down the toilet to see if you had a better job than him and then have a little smirk to yourself when you see that he’s fat and bald and his kids are weird looking.
You could connect with you family and friends to find out if people we getting married, or having a baby, or changing job, or moving to another country or something remotely interesting.
But not all identity thieves have gone "high tech." Many still use less sophisticated ways of stealing your personal information, such as looking over your shoulder when you're typing sensitive information or searching through your trash for confidential account information.
