There are a bunch of red flags here. It's possible this app has an ulterior motive.

At the top it says the author is Douglas Rushkoff but the avatar in the FB screenshot (under The Story) is Jacob Appelbaum's[1].

Here are the permissions it requests[2]: "publish_stream, email, rsvp_event, publish_actions, friends_online_presence, user_online_presence, manage_notifications, manage_friendlists, create_event, ads_management, xmpp_login, read_stream, read_requests, read_mailbox, read_insights, read_friendlists, user_work_history, user_website, user_videos, user_subscriptions, user_status, user_religion_politics, user_relationship_details, user_relationships, user_questions, user_photos, user_notes, user_location, user_likes, user_interests, user_hometown, user_groups, user_education_history, user_games_activity, user_actions.video, user_actions.news, user_actions.music"

There would be no point in requesting most of those if all you were doing was publishing a message or deleting content.

As PaulMest pointed out, apps do not have access to delete most of your content.
