title: Is there a way to delete all Facebook wall posts prior to a specified date?
body: <p>I've just inherited a long-neglected Facebook page with a deep backlist of spam and unwanted wall posts, which engulf the front page. I don't want to hide the entire wall, because I'm posting new content, but it will be a while before the new stuff bumps the spam below the fold.</p>
  
  <p>I know I can manually remove individual posts from the wall, but is there any way to delete posts in bulk, ideally before a specified date? </p>
