We recently added BTFS alongside Skynet, two decentralized file storage systems that provide incentive for hosting videos. We didn't properly announce it yet, but it's live on the site and you can use it to host your own videos.
The shooting video you are mentioning got dtube dns blocked in Australia for a good while. It was also pretty gore, and I overall had more people who asked me to take it down rather than the opposite. I don't think seeing heads blow up is what the world demands.
