This has the "makings" of DoFu all over it.
Care to enlighten?
I had a loan with Prosper Before DoFu, I made payments everyday using the proceeds from my loans. Even though I didn't need a loan, I wanted to see what borrowers go thru. My loan was paid off in 14 days.
The payment platform was designed prior to DoFu. I'm sure DoFu said prior to re-opening that he recommended changing the payment platform to replicate some place he worked before.
It forces those who wish to prepay to pay in full payments rather than smaller amounts. Thus increasing the chances of collecting more interest or forcing a borrower to ante up more than may have wanted to. Just my HO.
