This week, security firm Sophos tested Australian Facebook users to see how many people would add an unknown to their friends list. The tests were a repeat of earlier testing in 2007, where they found 43% of people blindly accepted a friend request from a made-up account belonging to a plastic frog.
The 2009 tests showed that we still aren’t being careful on Social Networks: approximately 46% of people blindly accepted friend requests from people they didn’t know.
So why is this a problem? Because you have a lot of personal information on your Facebook profile—by friending people you don’t know you may be setting yourself up for Identity Theft.
