Karl self-publishes a cookbook titled Hole Foods, in which he sets out recipes for donuts, Bundt cakes, tortellini, and other foods with holes. To publicize the book, Karl designs the Web site holefoods.com. Karl appropriates the key words of other cooking and cookbook sites with more frequent hits so that holefoods.com will appear in the same search engine results as the more popular sites. Has Karl done anything wrong? Explain.
