I played WOW for a few days till one day i found that some words in the in-game chat being transformed to garbled code, i know, there must be some key words  touched off  the in-game filter system then were banned.

Oh It may be the unique gaming experience only for players in China.  

As i know, many games (such as WOW, Auditon, etc. ) in China have this chat filter in order to keep every player away from curse, slander, four-letter word or something. But there're some other words were banned for the reasons you cannot comprehend, if so many words you cannot use to chat with others, can you still communicate with your playmates normally?          

Maybe i overdid my intension, because now many other players have begin to have fun with this special system, they tried every possible keyword they could imagine to test if it was banned by the system, and everyday they got new surprising discoveries. They found not only dirty words, but also state leader's name, name of publisher's competitors, and even in-common-used words such as: "system", "announcement", "Tibet"...- all of these - would be banned if you input them to the in-game chat. Then they collected these words up and created substitute for each. Yes they are doing and enjoying this work.

Well, a little sarcastic, but if you please, it may be a brand new joy of each game in China right?
