title: How to prevent modify and view user profile in Drupal 7?
body: <p>I would like to prevent specific user (or user group) to modify its profile in Drupal 7.
  That means that I would like to hook some function on the event when the user is about to display and change his profile.</p>
  
  <p>The best solution would be if he even could not see his profile, but I don't mean to secure by obscurity (hide the link), because drupalpage.com/user/X would always work.</p>
  
  <p>How can I do that?</p>
  
  <p>PS: perhaps there is any module to be able to achieve the goal without coding?</p>
