Which of these things would you feel comfortable putting on a billboard in Suwanee? Remember that EVERYONE can see it: your family, your neighbors, the local creepers--EVERYONE!
Your cell phone number?
A picture of yourself?
Party photos of you and your friends?
A list of all your friends?
A list of your after school activities?
Your location at any given time?
Chances are, you don’t want any of the above information posted for everyone to see! But, if you have an open Facebook page, you might as well have one of those billboards--except it’s not just the people in Suwanee who know all about you. Here are some facts:

This graphic shows how many people are able to see certain parts of your Facebook Page. The inner circle represents You (1 person). The next circle represents your friends (The facebook average is 130 people). The third circle represents friends of friends(8500 people). The fourth circle is all facebook users(350 million people). Finally, the last circle represents all internet users (1.8 billion).
Using the default Facebook settings, here is a sampling of how your information is distributed:
8500 people can see your wall posts, your photos, your likes/dislikes, your profile information, and your birthday.
350 Million people can see your list of friends
1.8 Billion people can see your name, your profile picture, your gender, and your networks.
Remember, these numbers are based on having only 130 friends!
Here’s something to think about: Let’s say the local weirdo is friends with one of your friends. He is creeping around your friend’s page and comes across your profile. Looking at your pictures, he notices pictures of you in your NGHS softball uniform and another of you standing next to the car you got for your birthday. The weirdo goes straight to the NGHS softball website and looks to see when your team is playing at home. So, now this person knows your name, what you look like, where to find you, and what you drive--all in a matter of three mouse clicks.
Now that we’ve got your attention, here is what you need to correct on your profile when you get home today:
1. Organize Friends in Lists
What do you do when your boss, mother-in-law, or a casual web acquaintance sends you a friend request on Facebook? Use Friend Lists. Friend Lists are the foundation of your Facebook privacy settings. Select Friends from the top menu, and use the Create link to create friend lists like Co-workers, Family, College Friends, etc. Your friends can’t see your lists, so you can name them whatever you like.
Tip: On your left sidebar, all your friend lists may not show up by default. Click More to see all of them, and drag and drop those you want above the separator.
2. Customize Profile Privacy
Click Settings > Privacy Settings > Profile. Select which parts of your profile will be seen by whom.
If you choose Customize in the drop down, you can be more specific. This is where the Friend Lists you created before become really useful.
Also go to the Contact Information tab and choose how you want your contact information to be shared on the Internet.
3. Set Facebook Privacy Level of Photo Albums
On the Photos tab of your profile page, click Album Privacy. Here again, you can use your Friend Lists to set the privacy for each photo album.
Note that your profile pictures go into a special album that is always visible to ALL your friends.
4. Restrict Search Visibility
Click Privacy > Search to set your visibility when someone searches Facebook for people. This is an important way to safeguard your Facebook privacy. You can also select what will be visible in the search results.
5. Control Automatic Wall Posts and News Feed Updates
Your actions in Facebook such as comments, likes, appear as highlights on ALL your friends’ home pages. You cannot use friend lists here, only turn them on or off.
Go to Privacy > News Feed and Wall and choose whether you want your boss or ex-girlfriend to know that you’re in a relationship.
6. Set Facebook Wall Privacy
Go to your profile page, click Options > Settings under the status box.
Here you can control whether your friends can post to your Wall, and who can see the posts made by your friends.
7. Avoid Appearing in Advertisements
Facebook has two types of advertisements: third-party and Facebook. Third-party advertisements are currently not allowed to use your pictures, but there is a setting to disallow it if it is allowed in the future. Go to Privacy > News Feed and Wall > Facebook Ads tab to turn this off.
The Facebook ads shown to your friends are about ‘social actions’ like becoming a fan of something. You can turn this off at the bottom of the page.
8. Protect Yourself from Friends’ Applications
Go to Privacy > Applications, and click the Settings tab and uncheck all the boxes. These settings control what information about you is visible to applications installed by your friends. By default, these are set to visible. This means that your religious, sexual, and political preferences, pictures, etc. are readily available to one of the million worldwide Facebook application developers, each time any of your friends takes a quiz, plays a game, or runs any other Facebook app. This is obviously a Facebook privacy issue.
This is the most commonly misunderstood aspect of Facebook privacy. These settings control what applications installed by your friends can see about you, even if you don’t install the application yourself.
Why is this important? Because these settings will not change anything about what you are sharing with the applications you install yourself. For that, go to the next step.
9. Privacy from Your Applications
There is no way to control what applications see about you; it is an all-or-nothing affair. Take this quiz developed by the American Civil Liberties Union to check what anonymous application developers can know about you and your friends each time you take a quiz.
The Burton Group’s Identity Blog features the Facebook Privacy Mirror, an application that you can use to find out what applications know about you and your friends. If you really want to see exactly what profile data of each of your friends is visible to application developers, Privacy Mirror shows it in detail.
The only thing you can do is to authorize only those applications you require and trust. Go to Settings > Application Settings from the top menu. Change the drop-down from Recently Used to Authorized. Here you can see all the applications you have authorized to get access to ALL your profile information. Remove the ones you no longer need.
Also check the list of applications Allowed to Post and Granted Additional Permissions to remove unwanted ones.
10. Quitting Facebook? Delete, Don’t Just De-Activate Your Account
You can easily deactivate your account in Facebook from the Settings page. But deactivation will retain all your profile information within Facebook, including pictures, friends, etc. If you want to permanently delete your Facebook account, click here to submit a deletion request. Note that:
1. There is an unspecified delay between submitting your delete request and actual deletion.
2. If you login to Facebook, your deletion request is automatically cancelled.
3. There doesn’t seem to be any way to confirm that your request was completed.
4. Even after permanent deletion, Facebook says that copies of your photos may remain on their servers for technical reasons.
Also, note that once in a while, there is news of a Facebook hack or leak that can expose your information on the Internet. It is better to be safe than sorry by avoiding using Facebook for anything that may embarrass you.
