Delivery companies just as guilty

I actually followed a link that one of the spammers sent (I suppose I have a small penis and was hoping a good dose of \/14gr4 would make all the girls love me).

They use world class courier companies to deliver their drugs. The UPS logo was emblazoned on the (illegal?) drug company website.

Surely these companies should also be pursued as they can reasonably be expected to know that they are involved in the illegal transportation of drugs?

I contacted our regional UPS division but they declined to comment.
