The Censorware Project: Exposing the secrets of censorware since 1997. “The Censorware Project was formed by a group of writers and internet activists in late 1997. Our goal is to
bring to light information about censorware products which is, by its nature, hidden.

… Censorware typically works by blocking you from receiving information — or by
preventing you from seeing it once it’s received, which has the same effect. But
it’s also censorware that blocks data flow the other way, typically by X’ing out
parts of your email, or preventing you from posting to a discussion website…

We at the Censorware Project believe that this type of software is the greatest
single threat to free speech as we know it on the internet over the next decade.
We are committed to exposing the flaws of this misunderstood software and
working to encourage alternatives to censorship. ” [via Red Rock Eaters]
