title: How not to set the user's email address in django social-auth
body: <p>I have django social-auth installed (from omab) and the users have an email address in database that is the one I want to keep but when the users log in from facebook using social-auth, their email gets replaced by the one they have in their facebook account. I am not sure the settings are the one by default or not and cannot find how to stop this behavior.</p>
