title: How to get a list of all retweeters in Twitter?
body: <p>I have seen numerous companies doing like Twitter lotteries where users got to retweet their tweet and then one of retweeters will get the prize or whatever.
  I was wondering now how do they get the list of all retweeters or pick the winner?</p>
  
  <p>I checked Twitter API and found only this thing: <a href="https://dev.twitter.com/doc/get/statuses/retweets/%3aid">GET statuses/retweets/:id</a> but it returns maximum of 100 retweeters. Is that the only way?</p>
