The larger and more aggressive debt collection agencies will have Uncle Sam looking over their shoulder in January. The new Consumer Financial Protection Bureau intends to rein in the abusive collectors and give harassed consumers somewhere else to go other than the overwhelmed Federal Trade Commission which previously had responsibility for keeping collectors at heel. Collection firms that follow the law will still be able to do their job; the C.F.P.B. is not a safe harbor for anyone with legitimate delinquent debts. Complaints about aggressive and illegal dunning practices have been the number-one consumer gripe to the FTC for years.
