title: Check if Instagram profile is private without authentication
body: <p>Is there a way to way to determine if a profile is private or public based on the public profile page it has on <a href="http://instagram.com/username" rel="nofollow">http://instagram.com/username</a>.</p>
  
  <p>I know there are ways but all of them require CLIENT_ID which I am not talking of. I need a way to differentiate private &amp; public profile just from the source of the profile webpage.</p>
  
  <p>I don't mind if it requires scraping data off Instagram.</p>
