Take the BlackHole exploit kit gang for example, they are out there for some time, renting and selling the kit, and at least one gang is responsible for the majority of the spams that are floating around, like "Your Flight Order NXXX", "ACH and wire transfer disabled." , " Scan from a Hewlett-Packard Officejet #XXX"... ALL of them contain a link to a hacked website that redirects to a "redret"...:)
