Interresting question. I think proponents would say something like 'if
the second would send spam the isp example.com would get a bad
reputation, no problem: a just switches isp'. In reality, if a has no
choice, a is just doomed or has to find another way to send his mail,
using third-party services.
Unless the reputation service is capable of more fine-toothed decisions
than just using the domain name (e.g., GOSSiP).
But how to decided how fine-toothed the decisions should be? If the decision
is always based on subdomains, then spammer.com just sends his first
spam-run
from 1.spammer.com, the 2nd from 2.spammer.com, etc..
