Yea you're right, nobody should ever profit from the heavily modified models that have complex vagina structures with deformation and such that often have a higher poly count then the rest of the model because its the focal point of a scene, while were at it nobody should be able to draw pictures of copyrighted material under commission!
You are completely ignorant of how copyright works, even if the models were ripped right from the game and not given a complex set of sex organ and custom bones for porn animations it would STILL be legal to charge money for content made with the models (selling the models themselves without significant modification is illegal though)
Nah what's gonna happen is that Blizzard will whine and complain and people will go 'there there" and keep making porn.
