I should have added that the preliminary extracted data is at:
http://spamcheck.freeapp.net/adult.domains.afterwhitelist
This is about 450k entries after whitelisting and some other cleanup. There are still a few bogus entries that would need to be cleaned up further.
The main problem is probably FPs; perhaps I should make it into a test list and ask people to see what kind of FPs they get. Unfortunately I probably can't run a zone file that large on my BIND nameserver (and I haven't converted over to rbldnsd yet).
