I think the idea is that you're supposed to proactively monitor your
systems for abuse and generally make your network inhospitable to
spammers, not just reactively move the customer to a new IP address
when the unpaid anti-spammers kindly let you know you've been

Personally I see SORBS as the canary in the coal mine. Except for the
DUHL (which identifies dynamic IPs, not spamming activity) nobody
serious relies on SORBS' data. So, it doesn't much hurt when they list
you. But, like the canary that dies first if the air turns bad, if
you're careful to watch SORBS you know when you're headed for problems
which will get you listed by a real RBL.
