title: tracking social media shares,likes,hashtags through a website
body: <p>i wanted to know if the following concept is possible.
  i am creating a website using PHP which tracks multiple users posts (hashtags,comments,likes) on  various social media such as facebook,twitter and instagram. </p>
  
  <p>The user needs to do registration on my website and whenever he puts a post/comments with a specific hashtag on fb,tw or instagram, my website tracks it and assigns some points to that user on my website. </p>
  
  <p>i have no clue if it is even possible. It would be nice if someone could help. Thank you.</p>
