title: Getting which users shared a post
body: <p>With the graph api, when I query for the feed of a user or page, there are some posts that have been shared by users, and I can see the data about the number of shares within the data section of one entity:</p>
  
  <pre><code>  "shares": {
      "count": 2
    }, 
  </code></pre>
  
  <p>When browsing facebook, on that post, when I click on the icon that represents "show shares", something pops up that lets me see some users that shared the post, according to the comment "You can see only shares that are public or from friends."
  So is there a way to get the user data from the shares with the graph api?</p>
