Critical for wide audience adoption
Steem needs to make sure adult contents are properly managed. This can be done in a decentralized way. People with reputation and tokens can vote it to mark it as an adult content. We do need to respect the sense of universal morality that exists in our society. So here is what I propose.
within the upvote/downvote arrow have another cool button for adult content. The swarm will decide if it's an adult content or not ( in a fully decentralized way). Then once a critical threshold of swarm input is reached ( Swarm consensus), the content will be moved to adult section. Before anyone opens the adult section there should also be age related warning. This is to just warn those who make a mistake by clicking. Sometimes there are things that can be cruel and inhumane that people can post and we the swarm need to have the ability to push that aside.
