Did people really sign up for this service without knowing it was being used to data mine? If so, maybe you should sit back and think about how you use the web. Companies have to make money, and it's free, so it should be assumed they are mining it. Also, stop being idiots and saying that they are sending your receipts. As far as we know they aren't. They are sending aggregate numbers. Just like the dozen other free services you're probably using right now.
