It makes fascinating reading as it shows that, while some registrars have obviously taken no action whatsoever following KnujOn's (pronounced without the "k", the name is actually "no junk" written backwards) 2008 publication, others have reacted strongly.
Top registrar on the KnujOn black list remains Xin Net. But the next 3 are now leading American domain registration companies eNom, Network Solutions and Register.com. This may be a dangerous place to be for those registrars.
Last year, when ICANN learned of the KnujOn top ten, it acted towards two of the highlighted registrars, Beijing Innovative and Joker. Under threat of loosing their registrar accreditation, both companies apparently did what was needed and have now disappeared from the KnujOn list altogether.
Registrars still on the list may want to react as well, lest they find themselves in breach of their accreditation agreement with ICANN…
