Some where out there someone may have the real tag on their car.
By keeping a registry of fake body numbers, how would you protect the innocent owner of the "borrowed" body number?
It is almost like identity theft.
Wouldn't be right to publish a list of bogus body tags by number.
You really should have the VIN of the phoney car also.
That info really should be compiled by the CRG, and kept private.
They can verify if you ask.
