Selling karma, hmmm...
They have 'factories' in China where low wage workers play online games to get goods and experience points that can be resold to gamers. So does that mean we will have Karma flaks begging for points so they can resell them.
On another note, I can see someone signing up for a hundred accounts so they can inflate their own karma

. At first it would be slow going, but after a few weeks they could be Karma King/Queen.
