check your privacy settings. Set everything to “friends only” until you are comfortable.
check your basic directory information (within privacy settings) as this is how Facebook shares your information with the world ie via google etc. One area in particular that you may wish to consider is who sees and who doesn’t see your friends list, so check >> “See my friend list”.
check your account for notification settings. You may wish to turn all the email notifications off.
be careful to only accept friend requests from people you know personally and who you are willing to share current information with.
be careful which applications you load. Some applications take you to third party websites. When in doubt, don’t use.
