Not sure why they don't just brute force their data out. Back when Google was hiding Google I/O redeem codes with goo.gl links, I brute forced thousands of links out of that shortener, just using 20 lines of bash script. I was just trying random codes and got one that led to a URL once per second or so. So I could pull down 300k links in a few days. Their case would be a lot quicker because it sounds like they have all the valid bit.ly links, just not where they lead to.
