Youre right it is hard to find information on them bu for me it is clear that they must use steem, how else can they actually play for content like steem does? They will have to fork steem and have their own image and video and dlive style front end where you can upload videos, earn vicepower and vice backed dollars actually an amazing name lol and it will just work great, you earn vicepower and vice backed dollars to sell , yu can power up vicepower or power it down and you can use your vicepower to upvote other vice creators, JUST like dtube/dlive and steemit NSFW section just advertised to the adult industry audience so it has GREAT potential and we get the airdrop free anyway ...
They just have to wait for HarFork20 to fork steem so they get all the great new features and no account creation bottleneck and hopefully communities maybe even SMTs :D
