Man, that China thing was pretty well done. The word filters were quite intelligent. Not only did "NG" turn into "China"--not only did URLs look like they went to "China.com"--but the actual URL targets didn't change. The word filter knew the difference between attributes of HTML tags and actual text. Neat!
