title: privacy settings of the Parse.com Anypic
body: <p>I read from the Parse site that it can be used to create a social network app with comments features. My question is how to set the privacy of the comments:</p>
  
  <ol>
  <li><p>Can I block one friend, if I block one friend, I can not see his or her posts on my homepage, vice versa.</p></li>
  <li><p>For Likes or Comments under a post: </p></li>
  </ol>
  
  <p>First, only the friends from my contacts will be able to view my Likes or my comments;</p>
  
  <p>Second: if I comment on my friend Bob's post and Bob has another friend Carl who I don't have in my Contact list, Carl will be able to view Bob's post but not my comment and Like to Bob's post.</p>
  
  <p>What will be the codes to do so? 
  Thanks a lot</p>
