I still believe that this might be a revenue stream for stuff like Twitter or Instagram. Just offer "VIP Badges" of several ranks from 5 to 500$ dollar a year.
Especially on Instagram there are so many people flashing their riches so there would be an inherent competition of who can afford the most expensive VIP badges. You post pictures of your Bugatti but you don't have that expensive black VIP badge? That's bad for your image.
There are also tons of "fitness models" who try to earn their livings through Instagram and some sort of VIP badge would give them a lot more "street cred".
Just be sure that you don't turn this into a micropayment shitfest and do some clever marketing which appeals to the public appearance of those rich Youtuber and then suddenly everybody wants to be a VIP.
