This blacklisting of the EU website is what led us to establish connections in China, notably with the anti-spam ISP DNSPOD. By having a separate website and network of concerned citizens who fight back against spam in China, the idea was that we could assure that our research and public safety documents could also benefit the Chinese people.

But, as many have noted, spamtrackers.hk is currently offline.
[Edit: As of Tuesday, the 23rd of October, the site is back online, following the conclusion of the congress]

There is a DDoS attack ongoing against DNSPOD, but this is only affecting a couple of the nameservers. The ability of DNSPOD to securely maintain their service and thus the resolution of their customers using DNSPOD nameservers should be applauded.

However, it is not the DDoS attack that has brought down spamtrackers.hk. This has been assured by the the state authorities, which have shut down the server (and many others) to help create a 'harmonious society' in anticipation of the 17th CPC National Congress (what's that?)

Hopefully, once that this congress is over, the server will be re-opened and thus allow Spamtrackers to help end spam in and originating from China. This would indeed help create a more harmonious society.
