title: Facebook Graph API: "Unsupported get request" when trying to get public information
body: <p>until now I thought it was possible to retrieve the public information of every user when making a get request to <a href="https://graph.facebook.com/user_id" rel="nofollow">https://graph.facebook.com/user_id</a>.</p>
  
  <p>But I just noticed a user where I am getting this as response</p>
  
  <pre><code>{
     "error": {
        "message": "Unsupported get request.",
        "type": "GraphMethodException",
        "code": 100
     }
  }
  </code></pre>
  
  <p>It's also not possible to get a custom profile-picture via <a href="http://graph.facebook.com/user_id/picture?width=100&amp;height=75" rel="nofollow">http://graph.facebook.com/user_id/picture?width=100&amp;height=75</a>.</p>
  
  <p>But the user/page can be viewed even if I am not logged in to Facebook. So I just can't access the public user information via the Graph API (without access token).</p>
  
  <p>I think the user might have (de)activated something in the privacy settings which disables retrieving public information with the Graph API. Do you know more about this? </p>
