That may be, but several of my classmates in grad school told me that they regularly wrote their papers in Chinese and sent them to a translating service for English. These were students who were conversational in English. It makes you wonder how much the translator changed the content.
I am not acquainted with the Chinese system, but here in India, you have to personally go to the designated test centers and take the test. At the center there is some Airport level frisking before you get to see your computer and you need to have your passport with you to prove your identity (if I remember correctly). You are also not allowed to wear jackets/overcoats/caps while taking the test. Really very little chance for gaming this system.
