Actually, Prosper has been scanning the system and checking for notes to buy back. I had several that were bought back, and it looks like a couple were removed from funding that were picked by my AQI and later funded, but my AQI picked wrong, and my investment cancelled.
If my filters had stood the test of time, I'd be agitating to get the new code up so I could continue to use AQI. But in my case, the two "iron-clad" "sure-thing" filters stopped finding loans to invest in. Maybe those loans are being swooped up by the API investors, or more likely, the underwriters at Prosper recognized the underwriting mistake they were making. In other words, borrowers were being offered higher interest rates than IMHO they should have. I was happy to have a piece of these loans, but now those lenders are being offered much better rates, so I don't get to see them anymore.
I love using the filters, but leaving a filter to run on it's own, means I have to be satisfied with every loan it captures. I haven't come up with a good combination yet.
