Not even the same thing. But yeah that's the risk you're taking. Though not in the context of "reaping what you sow".
Please explain how it's not the same thing. In both cases you're creating an account on an optional internet service that may have financial information.

In both cases, exploiting their systems and taking their data without authorization is illegal.
