My ISP already knows my name. Nothing else gets sent along. My bank account number is not useful unless they get my history from my bank. Which is not likely to happen. There's no 3rd party payment processor involved that could collect a bunch of my activity and then sell it to someone. With wire transfers, they'd have to go to everybody who I'm paying and ask for the data. Which is much less likely.
