That is again, not true.

Senderbase's listings don't correlate to any public information so it's pretty
much impossible to pro-actively protect ourselves from having our IPs set to poor.

You missed the point - if it was industry standard practice, reputation lists
at Senderbase, Spamhaus, and SORBS would *all 3* be out of business, because
the average spammer's lifespan at a provider would be less than the time it
takes the average reputation list to put up an entry.
