Well I kind of hoped I could pay IRS directly rather than through a middleman, or get a clear, no-loophole guarantee of some sort that they would do nothing with my SSN other than transmit it to the IRS. (Or through TurboTax, which I've unfortunately already used anyway, meaning they already have my info.)
