Yes i did follow the steps. It was back when the theory was first discovered, i found a setup that made it work. PapaGenos can confirm that i PM'd him about it at the time, and was the one who discovered that putting in names of DLC for other games such as Freedom Cry was bringing up the ad, thus confirming the theory i already had at the time that the characters were merely being linked to the concept of DLC by google.

I tried multiple names at the time and i clearly remember trying Erdrick, Luminary, Hero, Yuusha and Brave. None of them was bringing up the ad. Once i get home maybe i'll be able to screencap my Firefox history (if i didn't clear it for the sake of the setup, which is sadly likely to have happened considering it was one of the steps), but that's the most i can do in terms of providing proof.
