title: Get Reddit usernames of users who use a specific subreddit
body: <p>I would like to generate a list of usernames of users who use a specific subreddit.</p>
  
  <p>As far as I know, it is not possible to simply get a list of users who subscribed to the subreddit. If that's not possible, it would probably be the best to go through all threads and look at who has commented.</p>
  
  <p>How would I approach this?</p>
