I'm using tweepy to follow some people. I try following x's followers, and then y's followers . If there exists a mutual follower , I get the following error 

```
[{u'message': u"You've already requested to follow SOMEUSER.", u'code': 160}]

```

So I want to be able to understand whether a user is private or not depending on user's ID , so I can skip trying to follow them in my code. Is this possible ? The API Reference do not have the Object properties.
