Unless they own the IP, in which case it's ok to list, which we
would do.  In other words if we see in multiple
spams, we would tend to list it.

We may already have some collateral damage because of IP

Perhaps we should change the way SURBL handles numeric URIs to
include them only if the IP address also appears in SBL.  That
might miss some phishers though.

As a safety measure against uber joe jobs *against good guy IP
addresses* we should consider doing something like that.
