The following is a list of organizations and projects that we feel are particularly important in our mission to bring transparency to online censorship in China:

Every URL reported as blocked by Autoproxy users is also added to our GreatFire.org database for testing.

Their Information Revolution section publishes trends on censorship in China as well as leaks of self-censorship orders. We automatically import their list of keywords blocked in China into our system.
