Thought for the day: Ignorance

How come that every time an outage of Blizzard's servers in mainland China is reported, some people reply with comments about the effect that has on Chinese gold farmers? Isn't it blindingly obvious that if you wanted to shut out gold farmers of whatever nationality, you'd need to close down the US/Euro servers, not the Chinese ones? How do people imagine that gold is transferred from Chinese servers to US/Euro buyers?
