This is an intriguing idea. Rather than banning or blocking the use of content created by others, just automate the royalty payment system using a blockchain technology. It would be really cool if a database like Mediachain were directly linked to Steemit where the original creator is automatically paid a percentage of a posts earnings anytime the content is reused. This would be particularly useful for pictures, memes, video clips, and gifs. I, and most people on Steemit, attach a photo or gif to their posts to make them more eye catching. However, I usually have no idea who created the original gif most of the time. It would be nice to have an automated system that automatically paid the original creator a fixed percentage of a post's Steem payout anytime the content is used.
