My posting 20 registrars control 90% of illicit domains, says Knujon last Monday drew quite a bit of approval, and also a criticism of KnujOn's report for being incomplete. A more complete report that includes the methodology, the statistics, and the names is now up at KnujOn's site. Who are the 10 dirtiest domain registrars according to KnujOn? The list follows. For explanations, please refer back to the report

My posting 20 registrars control 90% of illicit domains, says Knujon last Monday drew quite a bit of approval, and also a criticism of KnujOn’s report for being incomplete. A more complete report that includes the methodology, the statistics, and the names is now up at KnujOn’s site.

Who are the 10 dirtiest domain registrars according to KnujOn? The list follows. For explanations, please refer back to the report page. Not surprisingly, the worst three registrars are in China. Number 4 is in Germany. Places 5 through 10 are held by U.S. registrars.

What would it take to clean these registrars up or shut them down?
