Advertising, despite the math and science introduced by the Internet, is still a visually driven purchase. Advertisers like to see their own ads within the right content environments. "Right" means not appearing in wrong places that result in an e-mail or worse, from the CEO. That is why porn has never been an option, despite the massive reach and consumer engagement this content category delivers. The line has always been porn, but any controversial edit can inhibit advertisers from advertising.
