Depends who owns the IP space, in the event the ISP has provided space
it¹s in your best interest to unblock them so if they get re-assigned to
someone else they work.
Again depends on what the customer is doing to continually get
blacklisted, I.e. Not fixing an issue they were told to fix, like open NTP
If the IP space belongs to your downstream customer, then it¹s their
problem, but still good to try and assist for a quality of service.

I'm working for a small web/mail hosting company.
I've recently noticed a lot of blacklisted IP addresses from NZ based
ISPs being dished out, part of our intrusion prevention methods involve
denying connections from these addresses.
How do these blacklisted IP addresses get unlisted? Is it the
responsibility of the customers of these ISPs or it is the responsibility
of the ISP?
