Evil Bandwidth Plot Exposed

We're still getting clueless people forwarding us email virus hoaxes. Pen-Pal, Buddy Frogs, Good Times, whatever. And I just realised who has to be responsible! Who has a motive for this "crime"? These things do no-one any real harm, they just take up bandwidth. Networks get saturated and maybe we have to buy more kit. It must be the router manufacturers. Maybe there is a secret team at Cisco or IBM generating new hoaxes to keep the email market growing.
