The big money in spam is not in selling Viagra, it's in selling spamming.
I'm acquinted with someone who does spamming for a living, mostly in the online casino segment. He does very well, and surprisingly polite company cares more about the money he has, than the way he makes it.
Replace "spamming" with "marketing" and that makes less sense. "The big money in marketing is not in selling Viagra, it's in selling marketing". Spamming is a form of marketing/sales, and Viagra is one of the products being sold.
