It's funny I was listening to something yesterday about how the Chinese wanted google or facebook to create a system so that all of someone's social media and searches would be tied to their phone number, isn't that exactly what steemit.com and the STEEM blockchain does?
The difference between a centralized network and a decentralized one is not that you cannot be censored or have your information stolen, it is that not just the centralized company can censor you or use your data, ANYONE can.
Power up a few hundred thousand STEEM and you can silence anyone you like. All the data is public so you can mine it all you like.
