ROKSO is the "Register Of Known Spam Operations", and it's a list of the top 200 spam sources in the world. To be listed in ROKSO, a spammer has to be terminated from at least three consecutive ISPs for Terms of Service abuse, and this cabal is collectively believed to generate 90% of the world's spam. This list is maintained by the Spamhaus Project.

By maintaining this registry, ISPs have an easier time researching new customers and (hopefully) not allowing one of these folks on their networks.
