title: How to get data to crawl reviews from any url page
body: <p>Suppose you have a play store comments page in which hundreds of people commenting regularly. My idea is to take data from the play store comments page not only on the same page but also when you're scrolling. 
  So it should take
  All the data from the comment pages 
  Who has commented on it?
  If he has given any ratings or not. 
  Including his/her photos. </p>
  
  <p>How do I approach this problem and what tools I can use for this? 
  Share all the links where I can read more about this type of problem statement.</p>
