Zaitcev, chalst: hjclub once posted a guide on piercing the Great Firewall of China (Google Translator - click on "Translate"), which is noble and everything. Maybe that's what made atai give him/her the certification. It's possible that hjclub simply doesn't understand English very well, and certified the spammer because (s)he liked the cute pandas. Don't ascribe to malice, et cetera.

Could any of the Chinese-speaking Advogato users out there convince hjclub to lift the certification?

Edit: I was wrong.
