Here's what someone messaged me:
"I downloaded ispoofer for Pokémon Go from tweak-box. Upon entering the game you have 2 black menu bars (part of the hack) the left one when clicked asks for you to Subscribe Now and Activate. When clicking Activate it brings you to a in game page saying to enter your License key. In blue underneath the text box (where you would put you key) it says “Get a license key”. When you click it brings you to a page and that’s where I clicked a link that said to contact you guys for a free permanent license key. "
So I don't know if that app is sending people directly to our page, or merely sending them on a google search, which is generic enough that it happens to show our page as top link.
