Nice. Lenders, you squawk too much and it's commercially reasonable for us to write off the loan.
Even better -- remember that loan by the Prosper employee who was using it as Prosper's employee education assistance mechanism? Or all the other loans by Prosper employees? So if Prosper wants to reward them for a good blog article or something, they all skip a payment, and on the 31st day Prosper simply writes the principal balance down to $0. Presto -- Prosper employee loan forgiveness!

ETA: Or here's another one -- For every borrower that goes 3 months late, Prosper calls and makes the following deal -- we'll write your principal down to $0.01 if you promise to pay that. Then Prosper reports the loan as "paid as agreed," and counts it as a PIF loan in its stats. No more charge-offs!
