The Nost Staff who unbanned the Chinese did a very honorable thing. They went through and left some banned who were guilty and unbanned the ones that they could not prove guilty. They had to have known how pissed off we would have been, but they did it anyway because they thought it was the right thing to do. Kudos to them for doing the right thing despite the consequences.
The only thing I don't really understand is that they now know they have an exploitable queue system. Even if the remaining players are not abusing it, the perception is that the Chinese are still wintrading. This system encourages cheaters and discourages those who do not.
I don't buy the Nost profits from Chinese accounts story. But, you could help dispel the illusion of corruption by making the queue system less exploitable.
