Support for all Google users would obviously be painful. I think it would be fair if there was some personal support for people who either spend a lot of money on Adwords (I think there already is?) or make a lot of money on Adsense. These people probably have the highest levels of stress due to "insta-evaporation probability", and no doubt the amount of support people would be several magnitudes less if you used a threshold like that.
