I think Fred is right (as usual). Although I would have like to see Prosper have to account to lenders for the many ways it screwed us (which the other lawsuit was designed to do), it was already and was going to continue to be a lot of work. Although I am not a securities expert (and TINLA in any event), my general understanding from things I read back when LendingClub first shut down over the securities issue was that the remedy for selling unregistered securities is that the buyers have the right to force recision -- i.e., Prosper may well have to repurchase all the loans (even -- and especially -- the defaulted/charged-off ones). That is such a huge hammer -- too huge, perhaps, since it will probably force Prosper into BK -- that the other lawsuit may just be moot, except for the curiosity aspect (while many of us would like to learn more about Prosper's shoddy verification, its apparent mishandling of the NAT cases, its ignoring its so-called "100% ID-theft guarantee, etc., in terms of making lenders whole, the securities case will do that to the extent of Prosper's available cash, insurance, possible deep-pocketed officers and directors, etc.).
But something else worth keeping in mind, is that the registration requirement for securities is intended to protect the investors from undisclosed and misrepresented risk -- something that lenders have certainly been victims of. Had Prosper complied with the law in the first place, it either would never have opened or it would have looked very different (perhaps like LC looks now -- only allowing sophisticated investors, no hyping of returns that "beat the S&P500," no instructions to lenders to bid their desired rate of return plus the Experian default rates, etc.) So in a very real sense, lenders HAVE been damaged by Prosper's failure to comply with the securities law. So it really isn't unfair to make Prosper and its officers and directors repurchase the loans that lenders may never have bought absent Prosper's unlawful conduct, even if that does rescue someone like Muleshoes who should have known better but apparently didn't.
