Note: These steps remove the access for all users. However, a Platform Manager can still edit each user's privacy/publish settings in Core > People Finder > [user] > Settings tab. If the Privacy option "Do not include my name or any information about me in the directory" does not appear on the Settings tab for a Platform Manager trying to remove a user from the directory, please review How can I hide a test user from the directory? for more information.
