In addition to what Aaron said, I'm obviously not talking about providing technical support for people who don't know how to search for things in Google. But services where an exchange of money happens definitely require adequate customer care.

There is an automated reason why this guy's having trouble. Google could easily look up a text string they've stored, based on that reason, and tack it on to the guy's account. Something more specific than the unhelpful low quality message he's getting.

Anyone who uses spamassassin, look at the X-Spam-Status header in a message, it could be that terse:

X-Spam-Status: No, hits=-100.7 required=3.0 tests=BAYES_20,HTML_MESSAGE,USER_IN_WHITELIST autolearn=ham version=3.002005

Which is much better than "too many points".

It would take alot of people but it would also increase revenues.

Adwords is not an intuitive service.
