A platform has NO legal liability for unpopular and or inappropriate content.
Steem is the platform. It holds all content.
A publisher has the tools to edit and censor unpopular and or inappropriate content.
Steemit, just like the tribes and other frontends, actually do "censor" inappropriate content. But, Steemit is bad at what it does since STINC is pretty hands off with it.
Some people have definitely uploaded really bad stuff here in the past.
Thanks again for your insightful and informative replies!
To add on to what enforcer said, I believe more in the platform than any one publisher. Steemit made clear they would censor with thedarkoverlord episode. But the blockchain holds it all, I believe its all visible on partiko.
Steem is infrastructure. Everything else is addon interface, and very pliable.
