Thoughts on enabling advertisements in exchange for Donuts?

If it was something I could turn on and off, then maybe. But then how would they track it? There are players who have more than one device, so what if they have ads enabled on their tablet but not their phone?
I think the idea about viewing an ad elsewhere in return for a donut is better. It could be one of the options in the donut-buying menu. Maybe enter some sort of code that comes up after viewing it online, since I'm not sure all devices could watch all ads. Yeah, I'd do that.
