You hit upon one of the most undervalued aspect to Steem. The ability for no text to be censored. It appears on the blockchain in the exact format it was posted. Nobody can alter or delete without a super majority from the Witnesses meaning that it will not happen.
People think that interfaces blocking something means it is not there. It is on the blockchain and can always be read in the native format. Even communities, when that is implemented, will give the ability to moderate but what is posted will feed through to the blockchain.
I do not know why serious writers who experience censorship do not at least cross post their content on Steem. This will give them an avenue where it is always out there. I guess it is the lack of knowledge of this platform.
censorship through downvoting can work - if your posts were part of your income...and you were downvoted for the content.
Incentives and disincentives to an action- is a deep part of the human psyche.
I wont screen shot my latest flagg- oneof which was as question of how to expand the steemit user base!?!?!? YES, SERIOUSLY.
Downvoted for discussing the expansion of steemit into new areas...! go figure..
