How to Make It Seem Like I Deleted My Facebookby Lara Webster
Facebook makes hiding your profile content very easy, but people will still be able to locate your profile and see your profile picture unless you take further action. Limiting when you appear in searches will stop most people from finding you, though your name still appears next to comments you leave for friends. To hide yourself completely from a user, you must block her.
Hide your profile in public search engines, such as Google, to make it impossible for someone without a Facebook account to find your profile. Go to the "Account" link in the top right corner of any Facebook screen and choose "Privacy Settings" from the short menu. Click on "Edit your settings" in the "Apps and Websites" section. Click on the "Edit Settings" icon next to "Public Search" and uncheck the box next to "Enable Public Search."
Stop people from finding you in searches on Facebook by altering your search privacy settings. Go to the "Privacy Settings" menu and click the "View Settings" link in the "Connecting on Facebook" section. Click on the gray icon in the "Search for you on Facebook" group and choose "Friends Only." Only your friends will be able to access your account via Facebook search, and to everyone else it will appear as if you don't have a profile.
Appear completely invisible to another Facebook user by blocking her. Point your browser to the person's Facebook profile and click the "Report/Block This Person" link on the left side of her profile, located below the list of her friends. When you block a user, you become totally hidden from her on Facebook--she cannot see your profile or any of the posts you create on other users' profiles and you never appear in a Facebook search. A blocked user may still find you in a public search unless you disable public search.
