Control Your Privacy on Facebook
Finally, click the Privacy Shortcuts icon (the padlock), select who can see my stuff, and click the Use Activity Log link. Then seek out and cut any ties to Facebook content you don't want to be associated with.
The Activity Log is a reverse-chronological list of everything that has been linked to your Facebook page, including your posts and pictures and likes, tags of you, your comments on other people's Timelines, and posts created on your behalf by the apps you use. For each item, you can choose who sees it on your Timeline. You can also "Unlike" an item here by clicking the pencil icon on the far right.
These changes apply to individual items, not to the settings of applications. To change application settings, select the app from the list in the left-hand navigation and then change the sharing setting(s) at the top of the screen.
