Considering HoloZing paying 7.5% to delegators, I'd say it is more than fair. Most posters probably delegate too, it's a sneaky way of getting extra return but you would have to make quality posts. I do it with @worldmappin , where they at least power up your share of the delegation rewards so it would take a while to power that down and profit.

One day I will post in HoloZing too, but for now shhh!
