Query: I would never buy this, or any other book by Allen because..

I receive so much spam from Allen, or from people hawking his "get rich quick" schemes, that buying anything written by this guy, even if he is a "genius", would only reward bad behaviour thus making me party to the scourge of spam. Since I have no desire to be part of the problem, I choose to be part of the solution by not buying any products or services from those who spam, even if the products or services would otherwise be interesting, not to suggest that Allen's is."Multiple Streams of Internet Income: How Ordinary People Make Extraordinary Money Online" - in a word, spam! If Allen was such a maven of marketing, he would not have to alienate huge swaths of the population to achieve his goals.
