Using a Weak Password
Avoid simple names or words you can find in a dictionary, even with Posting Your Child's Name in a Caption
Don't use a child's name in photo tags or captions. If someone else does, delete it by clicking on Remove Tag. If your child isn't on Facebook and someone includes his or her name in a caption, ask that person to remove the name.
Mentioning That You'll Be Away From Home
That's like putting a "no one's home" sign on your door. Wait until you get home to tell everyone how awesome your vacation was and be vague about the date of any trip.
Letting Search Engines Find You
To help prevent strangers from accessing your page, go to the Search section of Facebook's privacy controls and select Only Friends for Facebook search results. Be sure the box for public search results isn't checked.
Permitting Youngsters to Use Facebook Unsupervised
Facebook limits its members to ages 13 and over, but children younger than that do use it. If you have a young child or teenager on Facebook, the best way to provide oversight is to become one of their online friends. Use your e-mail address as the contact for their account so that you receive their notifications and monitor their activities. "What they think is nothing can actually be pretty serious," says Charles Pavelites, a supervisory special agent at the Internet Crime Complaint Center. For example, a child who posts the comment "Mom will be home soon, I need to do the dishes" every day at the same time is revealing too much about the parents' regular comings and goings.
