Irrepressible.info is a campaign by Amnesty International to fight internet repression in countries like China, Iran, Myanmar, Tunisia, Uzbekistan, Syria and Vietnam. You can participate by publishing censored material from their database directly onto your site. Sounds like you're hosting web content as a workaround so that people will still be able to see it, but actually it's just a way to advertise their campaign by showing examples. Still sounds cool. Look at the narrow column to the right and scroll way down.
