Coming from a place where this practice is banned, I wonder how they implement this. Traffic going to certain IPs or IP ranges is exempted? They mention WhatsApp and Twitter, and the first thing that comes to mind is using them as proxies to tunnel through. I don't think it would be against ToS either - you're just asking someone else on the "other side" of those services to access the 'net and get the information for you, and it shouldn't matter one bit if you're speaking English or TCP/IP. :-)

(There's plenty of info on the internet about wanting to use these services while behind a proxy, but seemingly none on using them as a proxy...)
