I saw the update and I'm one of the ones who turned off automatic investing. With only $6K in the account, I'm not overly worried; they can still service the debts if the company goes under. Their collection practices need some work though, even if it meant a small uptick in fees for the service. Calling someone every weekday during work hours and not leaving a message doesn't do much in way of getting a customer to come back to the table and catch up on payments.
Like others have said, it's an investment and I'm getting 8%; not bad considering the charge offs.
