Facebook has two ways you can remove the content you’ve posted to the site in bulk: account deletion and deactivation. Deleting your account permanently erases everything you’ve ever posted to the site. Deactivation hides your profile and posts from view, but the content remains stored in the site’s database. With a deactivated account, some of your activity still appears to your friends. Writer Bio
