He finishes by saying "It's possible that they didn't just implement this on a domain level, but instead stripped the sites that linked to AutoInsuranceQuotesEasy.com of their ability pass juice. That would mean that if you were duplicating this site's links, you'd be out of business too. Always weigh the risk against the reward and NEVER gamble with a client's site without getting approval (in writing) from them that they are comfortable with the risk of losing all of their rankings."
