i'm not sure how much "zillions" is, but it's not at all clear to me that it's large enough for spam to remain profitable if they use their own machines. i suspect the difference in computing power is only 100 or so (you can get low-power servers using atoms...) and that a spammer needs to send millions of emails to get an edge. however, it doesn't work well against bot nets (and i think that's where most spam comes from).
