backed_projects returning nil
First, thanks for the api!
I've been playing around with it and I keep getting nil for backed_projects but when I do backed_projects_count I get the correct value, 115.

Did some investigating by forking the repo and it seems like we are forbidden from using that endpoint.

Hmm... no, I'm not sure what's causing that. I know that since the time we made a lot of that functionality, Kickstarter has changed their API responses quite a bit, so I'd guess that kickscraper just isn't processing that call right.
If you feel like looking into it and submitting a pull request, go for it!
I don't know that this is a code issue, this is what I got when I went to the url in client.user.urls (backed_projects) in a browser:
