It is completely on topic for the reasons you state.

In general,  announcement on Spam-L and NANAE that the ownership of IP address 
space has been taken over by new non-spammer user will cause many or most of
the blocklists to remove the previously offending addresses.   However some 
blocklist managers don't follow these groups assiduously, some blocklist 
managers have a several-month waiting period, and some blocklist managers have
a policy NEVER to admit traffic from any once-polluted address space, possibly 
because they have been lied to so many times.

So there is NO universal retrospective solution.

Therefore, and this is the simple point I have been trying to make here,
there remains only a prospective solution.    That is what you have to face,
and face now, because the use of blocklists is growing rapidly and possibly
exponentially.  It is the only defense we victims have against the present
irresponsible management of IP address space and domain names.

The RIRs are responsible for the proper management, express and
implied, of the IP address space allocated to them.  Since recycling of
IP address space obviously will occur over the years, decades and 
centuries, the RIRs have a duty to prevent pollution of the resources
they manage.  The pollution comes from spamming.   This means the RIRs
have to have a clear policy that IP address users must not spam, must
not allow spammers on their networks, and must have hair-trigger management
systems in place to identify incipient spammers and penalize them (because
blocklist additions can occur in days).  (All this is eminently doable now
by presently existing technical measures, and many ISPs do indeed use such
measures.)  Any user who violates this rule must have his IP address space 
withdrawn. That is the only sanction that anyone will pay attention to.

In short, the RIRs have to take on a role to act, probably agggressively
and violently, against abuse of the resources they manage, by the people
to whom they entrust these resources.   If you list members are not willing
to rise up and force them to prevent spammers from pissing in the pool,
then don't complain about how the water tastes when you swim in it.  It
is the result of your own (in)action.
