We cannot really confirm that your post is 100% accurate as some countries are still questionable when it comes to the legality of cryptocurrencyu especially Russia and China. If you will look at the Alexa rankings of popular Bitcoin faucets you will always see that Russia is in the top 3 visitors of that website, which means that this websites are not blocked by the Russian government, their citizens can even use cryptocurrencies freely without being apprehended by the government. In China you will see another point where two of the top 10 cryptocurrency exchanges are operating inside China namely OKcoin and Huobi, now if cryptocurrencies are illegal in this country why are we seeing companies like this operating freely in that country?
Well, Russians, Chinese, Iranians... all those ever forced to find ways around state censorship and restrictive freedoms of access, they're probably a lot better informed than some of us in circumventing firewalls and ISP blocks. Plus, the Russian government hasn't exactly will to deploy the resources for a crackdown, which people would anyway find ways around. Look at Iran's recent experience, and Venezuela before that. Tried to ban it, tried to block access, but people found a way, and P2P trading thrives.
Impossible to block faucets and other sites who'll just put up mirrors.
The Chinese ban in on yuan trading... you're still perfectly fine to to crypto-to-crypto, and if you're in Hong Kong, autonomous jurisdiction presides.
