Anyway, how does BT's cleanfeed work? How are British 3G operators doing equivalent blocking? I'd be interested in learning about the implementation.
Well, first of all Cleanfeed's not perfect. And it's not that secret either. http://www.cl.cam.ac.uk/~rnc1/cleanfeed.pdf --Michael Dillon P.S. Although I work for BT, I have no involvement with the group that is repsonsible for Cleanfeed. All that I know about it, I learned via Google.
