Haha. Well, I'm actually in the business of consulting people AWAY from using techniques utilized by many companies in the SEO industry. I tell my client to ignore the noise and focus on quality content creation. I just understand that business is by nature not necessarily an ethical venture. It's an evil that we either accept or delude ourselves into believing we're actively opposing. If poor ethical standards in an industry gives you pause, then most people should take a look around their houses; our closets, shoe racks, refrigerators, cars, computers, electrical outlets, etc, etc, etc are teeming with the evidence of poor business ethics in pursuit of that filthy lucre. Once again, just my opinion.
