Blacklisting for an ISP is not a good thing but it can also be used to
advantage.  Designate one subnet as 10complaintsPlus or some such
'trouble' list.  Assign this user and other 'trouble' hosts to this
subnet.  Just to save bandwidth, you have some need to scan for virus
symptoms and other problems.  When you 'smell' a problem you might
disconnect then move that host to a quarantine net.

The value of this is that spam detectors can detect the source IP address
and increase the score on the other end of things.  In this way you do 
not need to terminate service.  You will have made one step toward 
cause for pulling that service.

The trigger for action would be complaints in addition other policy based
review (perhaps bandwidth).

The alternative is that all your nets would be blacklisted because 
of one user.
