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. I.e. when Senderbase assigns IPs to poor, those same IPs aren't listed on any RBLs or anything. They operate in a vacuum where there is no visibility into why they do anything. Unlike organizations like Spamhaus where you know exactly why IPs are listed.

That's just not true, we would much rather be notified of something that a reputation list finds objectionable and take it down ourselves than have Senderbase set a poor reputation on dozens of IaaS customers.
If it was industry-wide standard practice that just notifying a provider resulted in something being done, we'd not need things like Senderbase, which is after all basically a list of people who don't take action when notified...
