So hypothetical here. If Dreddit did launch a system that made it so users could trade Karma in for real currency or some alternative, does that mean that all fan fictions and all other fan boy account created material would become copyright infringement as they are now making money off the original works?
Nah, it would mean that you cannot copyright a work created by an AI, such as a piece of art.
E.g. if you tell it to draw you a donkey carting avocados, the picture can be used by anyone from what I understand.
