I asked about whether one website offering a free AdSense coupon was sponsored by Google or not, and I received contradicting answers.
Edit: The website was www.googleadwordspromos.com/ and an example of conflicting answers is here: http://www.google.com/support/forum/p/adwords/thread?tid=62a...
This has been the case with Google forever(and discussed on HN multiple times), you get customer support if you are notable or raise a big enough stink.
Reason Google does it, is because they are not a customer centric company, they are engineer driven company(or at least used to be, what they are now is an open question). They save serious amount of money by not having human employees evaluate each AdSense account on case by case basis.
Just don't put all your eggs in Google basket is all I can say.
