Disgusting. The worst part? Even if Blizzard shut down China's access it would still go on. It just wouldn't be WoW. I imagine it's pretty effective: Work them until they can't stand, and then sit them down and work them until they can't even sit up. Beat them, leave them unconscious for awhile, rinse and repeat.
What can you do? What can anyone do? Every time I hear that they crack open the door for journalists, and then journalists start getting contained, I don't even want to think of it. I know a woman who is Chinese-American who loves her heritage (she is majored in Chinese/Japanese/English languages) who went there for a year teaching trip. We had to be careful on the website we all go to or else it would get blocked for violations (mentioning/mocking China's govt, cussing, speaking your mind etc). Happened at least once a week that it would get temp blocked.
I sent her the article link, I wonder what she'll say. I'd say she's probably the most aware person of China's duplicitous nature that I know.
