The problem is that the chinese community can make profit out of the realm, one big reason out of many why they're here. They can sell gold and services on sites. Also any piracy or private server of a game is illegal in china, thus making private realms being attacked by enforced law since early 2014 and even players on those realms can get penalized. Not to mention that the only way they can connect to this realm or any other piracy realm is through VPN, which is also highly illegal in china.
Should start some kind of a petition to the chinese government to end this menace.
