@forthy I know how the #GreatFirewall works - I've been paid to penetrate it from both sides on several occasions.
Also that HK - SIM trick doesn't work and whilst it's tempting and relatively easy to get SIM cards with fake IDs everywhere, I think just setting up a local "probe" i.e. #Pi0W with some extra hardware that is using public WiFi's is a mopre practical option to do so.
That being said, most clients just flatout geoblocked the "P.R." China as well as North Korea and Russia...
