censorship - Banned words analyse

The sage of the banned words on the Chinese internet goes on. ESWN has now analysed many of the words and the overview is rather fascinating. The interesting thing is that I can read his page without any problem here in Shanghai, while the filters stop me from reading a similar page at the China Digital News. Makes you wonder how it actually works.
I wonder how it works when you are in the middle of a chat and you use a banned word. Are you kicked out of the service? This list makes the Chinese ability to replace banned words with many of their homonyms even easier.
