title: Identifying deleted posts and comments from a page in FB using API's
body: <p>In one of our requirement using fql we are collecting posts from fb page.
  I have to identify <code>deleted posts</code> from the page to remove those post from our storage based on the fb data usage policy.</p>
  
  <p>I tried to get deleted <code>post_id</code> using <code>is_hidden</code> but it is not showing deleted post_ids.
  The only option i have is to keep a track of all <code>post and comment ids</code>.</p>
  
  <p>Please let me know if their is any other way to get all the deleted posts and comment ids using some API's or any tool.</p>
  
  <p>Thanks in advance.</p>
