Check out Eclipse Phase. It's a transhuman cyperbunk eldritch horror RPG. One of the core ideas is that the Anarchists living out past Jupiter use @rep, a social credit system where your ability to borrow stuff or get time on the community 3D printer is a function of whether people think you're cool or not.
