A. Precisely the same people that were doing it before!
I just noticed this article on TechDirt, to me it doesn’t make any sense, perhaps they misunderstand how gold farming works.
Here is there article: But Who’s Doing All That World Of Warcraft Gold Farming While WoW Is Down In China?
The topic basically says it all, but the fact is that chinese gold farmers aren’t making their money from farming gold on chinese servers. The reason that gold farming is profitable for them is not due to it making a lot of money, but just due to it making more money than some of the average jobs around there. By selling the gold to Europeans and Americans for prices they are prepared to pay (a quick google suggests around $10/1000gold) it gives these gold selling businesses a cut and passes some of this on to the farmers. They will only make a few dollars an hour, but citing this 2006 article which points to “An average Chinese wage of $0.57 per hour” this doesn’t hold up that badly.
Obviously this means that these gold selling companies exist to sell to WoW players in other regions, people in China don’t earn enough to pay these prices and domestic gold farming would not be profitable due to the much lower wages.
So in summary, the Chinese WoW servers being down makes zero difference to the gold farmers, they aren’t farming on Chinese servers anyway!
