Hi, and welcome. I just want to make one quick clarification, there is a difference between the Steem network/blockchain, and steemit.com. It is practically impossible to ban or censor anyone from posting absolutely anything on the Steem network. Steemit.com is one user interface for interacting with the Steem blockchain. It is run by Steemit, Inc. which is a US based company and therefore could be forced to comply with censorship requests from the US government for example. However, there are and will be many more other applications for interacting with the Steem blockchain, thus it is technically very difficult to actually block or censor anyone.
