Your summary is scary. I didn't think it through enough, obviously. Had Prosper's position been accepted, lenders would be on the hook every time PROSPER did something wrong. It's bad enough that I'm losing money here; it would be utterly unforgivable if I faced personal liability because of this. Prosper's position, in addition to being sanctionably false, is a violation of its fiduciary duty to its lenders. Outrageous.
Thanks, Fred, for your efforts to keep Prosper honest. Too bad they're doomed to fail.
