H.R 7661 is a bill that's been introduced in congress that will prohibit this practice.   Please sign this petition to show your support. 

Detail: This bill prohibits credit reporting agencies from providing a credit report not initiated by a consumer if the report is being provided on the
basis that the consumer has had a credit inquiry regarding a home mortgage loan. This practice, known as producing a trigger lead, provides notice to other mortgage lenders that the consumer is seeking a mortgage loan.
