title: how do you get follower ID's of people who are not following you Twitter API
body: <p>I have a list of tweets with information about the user who tweeted them that I am using for an undergrad research project. To build a social network graph of these tweets I need to grab their friend and follower lists. I have tried using the GET Follower IDs call through the twitter4j platform. My authentication is Oauth with Read, write, and direct messages. I get a 400 response code with no further error code. I also get the following exception code</p>
  
  <p>exceptionCode=[92c30ec6-19bed99c 70a5018f-1e1c55ac 70a5018f-1e1c55aa], statusCode=-1, message=null, code=-1, retryAfter=-1, rateLimitStatus=null, version=3.0.3}</p>
  
  <p>This tells me that I'm not authenticated to make this request which from what I have read is because the people are not followers of mine. Is there a way I can request this information without having this relationship with the user?</p>
  
  <p>here is my code </p>
