I report them as an item encouraging illegal activity, seeing as they are basically selling a ringing kit.
Whilst there is no law about selling one, I was under the impression that the V5c remains the property of the DVLA and must be surrendered if the vehicle it refers to is scrapped. So does that mean technically the V5c is stolen property any point after?
