If it's still visible on the blockchain, then how is that censorship? I am reducing visibility on Steemit in an attempt to discourage that behavior. I want this site to cater to everyone, but at the same time I know the masses will be more hesitant to join if this become a new porn hub. This is why we need different windows, as @dwinblood said, to the steem blockchain that can view niche content, like porn, that doesn't fit Steemit's culture.
