No point.
First, a DV is sent when, as stated in FDCPA 809(b), the consumer notifies the debt collector that "the debt, or any portion thereof, is disputed."
Once a debt has been paid, there is no more debt.
Second, even if timely, the effect of a DV is to impose a cease collection bar on the debt collector, which remains in effect until such time as they choose to proivde validation. Payiment of a debt terminates continued efforts to collect on a debt, thus making a cease collection bar redundant and meaningless.
Third, there is no period for or requiremnt to respond to a request for debt validation.
With their collection activites terminated by payment, they could care less about responding, and can simply chuck in the trash.
There is no such thing as deltion for lack of response to a DV request.
