As the sub-poster mentioned, shadow socks is designed to counter it. What is interesting is that the author (mainland Chinese) had a 'visit' from the 'police', who 'asked' him to abandon the project. He changed the default branch of his GH project to an empty branch, but the code still remains. Further, although his code is known, the GFW doesn't block its techniques.
