There is a loophole in the above argument. Some of the ISPs charge by the amount of traffic an individual user uses. If a spammer uses a zombie operation and starts sending spam from these zombie machines, it increases the net amount of bandwidth the user uses, resulting in higher internet bills, and hence more income for the ISP. So shutting down the zombie computers will infact result in reduction of revenues for ISPs.
Are you assuming that the zombied machines are also the ISP's customers? Celejar
