“This is why email spam has become such a problem — it costs nothing,” she said. “If people can put out 12 versions of a single book under different titles and authors, and at different prices, even if they sell just one or two books, they can make money. They win and the loser is Amazon.”

It would require a redesign of the Internet to eliminate free email, but it seems like Amazon could control this. Maybe they will soon.
