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?
