The major RMT sites, especially those that advertise in game are not Asian run. Most of the users who trade out on the normal western websites that get their items from botting are not Asian. Yall are so xenophobic it is funny. Like sure there are some, but no more of less on a per capita basis than western users.
And your ideas to prevent cross realm will stop near zero of the users who wish to sell botted goods on western servers either.
