As I commented in a thread below, I had started using your service connected to a debit card via my credit union. Then was required to attach a bank account/routing number as the source for funding and didn't receive an adequate answer as to why (which is fine, but it's slower to process and it requires that I provide more sensitive information). I get that Privacy is obligated to gather certain financial information for regulatory purposes and fraud prevention, but it feels like I'm widening my attack surface providing that info.
