I mean, I had a development flag where it wasn't serving real ads when I was in development mode and the copy I had installed on my own phone had the IAP active to remove ads. There is no chance I was clicking my own ads. The revenue from ads was literally peanuts anyways, I don't even think I ever saw a cent of ad revenue (you have to hit a certain amount before they will even send you a check) the ads were basically only there to get people to pay the small one time fee to remove them.

If I did get an ad payout, it was likely < $100. I honestly don't remember, I've put so much of this out of my mind.
