title: How can i validate my users social profile links
body: <p>I have a problem with social profile link.</p>
  
  <p>How can i force users to add valid and existing social profile links.</p>
  
  <p>Each user can add their Facebook, Twitter and LinkedIn Profile Link but i see, they add for twitter '@ProfileName' instead of <a href="http://www.twitter.com/pagename" rel="nofollow">http://www.twitter.com/pagename</a> and some users added 'Facebook Name'(John Martin) instead of '<a href="http://www.facebook.com/johnmartin" rel="nofollow">http://www.facebook.com/johnmartin</a>' and same for linked in.</p>
  
  <p>I try to find a best solution but i can't.</p>
  
  <p>Can anyone give me a good solution for this issue?</p>
