Beware of folks sending you friend requests! It is generally a VERY ATTRACTIVE young person... but you don't really know them. Their info shows that they are from your local town. They have even checked in at local places, but if you scroll all the way to the bottom of their news feed, you will notice that they have just recently created their profile... and they aren't who they say they are! So when you add them as a friend, these scammers then have access to YOUR personal info, your news feed, photos, etc! It puts them in a better position to scam you or steal your identity!! It is pointless to have security settings if you add unknown people to your friend list!
