title: Facebook returning The user hasn't authorized the application to perform this action for half of the users
body: <p>I have an app that is public to the world (not dev mod).<br>
  I have 1000 users registered in the last 4 weeks with the permissions <code>email,publish_actions</code>.<br>
  The problem is, in the <strong>first</strong> attempt to post in their feed I got an error for <strong>half</strong> of them: </p>
  
  <pre><code>{"error":{"message":"(#200) The user hasn't authorized the application to perform this action","type":"OAuthException","code":200,"fbtrace_id":"FSQbqGwg8WC"}} 
  </code></pre>
  
  <p>Why am I getting this for half , I dont think its related to code because half of them are ok.<br>
  I am not a spammer, this is the first attempt to publish something so it cant be that 500 remove them self from the app.</p>
  
  <p>thanks</p>
