How to Know if You Are Being Stalked on Facebook
Learn how to know if you are being stalked on Facebook so you can cut off communication with other users who are harassing you. Although the accuracy of third-party "visitor tracking" applications is disputable, a friend who is truly stalking your Facebook profile leaves traces of his presence. Prevent strangers from stalking you by adjusting your Facebook privacy settings.
Check your Facebook notifications frequently for suspicious activity. Whenever a friend posts something to your wall, comments on one of your photos or interacts with your profile in any way, a notification displays in the upper left corner of the window. If someone you barely know or don't know at all frequently posts to your profile, chances are high you're being stalked.
Be wary of people you don't know well who frequently send you chat or email messages on Facebook. If someone is eager to talk to you but doesn't have a reason for wanting to converse, he may be a stalker.
Monitor your friend requests for suspicious people you don't know or recognize. In particular, if you deny one suspicious person's friend request and one or more additional suspicious requests appear shortly thereafter, it's possible the same person is attempting to add you using different false Facebook accounts.
Click the "Account" menu that appears in the upper right corner of any Facebook screen and choose "Privacy Settings." Choose "Customize Settings" from the "Sharing On Facebook" pane to adjust who can see personal contact details, as well as who can see and comment on posts you make -- for best results, limit as many details as possible to "Friends Only." Alternatively, click the "Edit Your Lists" link under "Block Lists" to add known stalkers to the block list, which prevents them from communicating with you on Facebook or even seeing your profile.
