The Status Reports (PDFs) down the page are statistics, updated quarterly.

At the top of the page is the delegated-extended daily report.

"The file delegated-extended contains a daily updated report of the
distribution of Internet number resources.

The resources reported are:

IPv4 address ranges (IPv4)
IPv6 address ranges (IPv6)
Autonomous System Numbers (ASNs)"

That file is text.

The lines for IPv4 look like:
apnic|AU|ipv4|1.0.0.0|256|20110811|assigned|A9173591|e-stats
apnic|CN|ipv4|1.0.1.0|256|20110414|assigned|A92E1062|e-stats
apnic|CN|ipv4|1.0.2.0|512|20110414|assigned|A92E1062|e-stats

The Readme file explains the fields:
http://www.nro.net/wp-content/uploads/nro-extended-stats-readme5.txt

4th field is start IP
5th field is number of IPs in block
6th field is date of allocation/assignment

I would think that file might be parsed, compared to RBL listings, and
if listing date (or last bad behavior date) < allocation/assignment date
- then remove listing.
