A CD issued by the Church of Scientology to its members contains a hidden filter designed to prevent them from using their Internet connection to read a wide range of web pages, email and newsgroups which contain words that the Church of The CoS censorware filters out a number of well-known critical sites, by making it impossible to connect to URLs with certain combinations of characters in them. Secondly, certain words are filtered out of the data stream and replaced with spaces, including the names of ex-members of the organization. One of the more interesting effects is word chopping, notably any configuration of "not" and "s" is deleted. This means that "not sure" becomes "ure", and that "not surprised" becomes "urprised."
2. Most people are completely unaware of the extent of the daily hidden censorship of the media - every critical book, film, article and piece is submitted to libel lawyers for checking before publication or transmission. Most of those which carry any risk of leading to a libel writ are simply pulled and binned. If something is published and results in a writ, generally a humiliating apology or settlement is made to avoid the massive costs of a case.
