Quote: Virtually all traffic came from mobile devices in China
I suggest we build the Great Firewall of China. A great Firewall of Ukraine and a great firewall of ex-Soviet Union would be a good idea too.
Real Ones. On the _OUTER_ side. Anyone uttering the technically impossible world should think twice - it is possible to dump _ALL_ traffic from those locations for 3-4 letter agency perusal and analyze it. If that is possible, it should be technically possible to filter it too.
