I have also come to this conclusion. I think Google is planning not only on selling directories of names to advertisers, but selling a vague sense of trust associated with being around friendly people. That is, they're looking at a marketing demographic who will feel vaguely reassured by seeing "standard", Anglo-American names. They will see adverts in proximity to lists of names similar to those of their friends, and feel more inclined to buy the products being sold. That's why Google are suspending accounts on the basis of really crude pattern matching, even though they must know perfectly that, y'know, some people are Asian American or Hong Kong Chinese or have names that sound like common English nouns...
