So if the debt can be "bought" for pennies per dollar, why can't it be settled for this amount by the unfortunate people at the end of the bludgeoning stick?
You know what would be fun? A site that lets people get together and buy these debts and then instead of hounding the debtors, forgives the debts and then sends a nice card informing the debtor that they are now forgiven this debt with the names of all of the people who kicked in to wipe it out.
