Graph Search makes it unbelievably easy to search photos of you posted by someone else, and more often than not, these photos are on the not-so-desirable side. Protect yourself from this kind of unwanted exposure by visiting your profile page and clicking on the Activity Log link located on top of your cover photo. Click on Photos then check out Photos of You to see pictures your friends tag you in. On the top of the list, click on the Shared With dropdown menu to find out which of your photos are available to the Public, your Friends, or Friends of Friends.
The ones viewable on Public mode are the ones that really need attention. The photos that normally show up are Instagram photos shared on Facebook and photos posted by friends who have lax privacy settings. While you can’t really tell all your friends to beef up their Facebook security for your benefit, you can request them to take down photos of you that they posted. The least you can do is untag yourself and enable Tag Review in your Activity Log so posts by friends that involve you won’t immediately go up on your Timeline without your permission.
Now that you know you are susceptible to a Graph Search based on your personal information, visit your About page through your main profile and go through each section meticulously. Click on Edit and make sure everything is viewable by your intended audience – choosing Friends only for all the sections is recommended.
