Google Adsense allows companies and content producers to advertise and generate revenue on Web sites and youtube videos. But, did the search engine giant steal from its customers and video producers? A firestorm of controversy has erupted over allegations made by a person who says he was a Google employee. The company quickly denied the allegations, saying they did not engage in unscrupulous behavior. According to the source, Google ranked each content producer by a color code, indicating how much the company earned each month. The Google Whistleblower published his case online stating "We were told to go and look into the publishers accounts, and if any publisher had accumulated earnings exceeding $5000 and was near a payout or in the process of a payout, we were to ban the account right away and reverse the earnings back." According to the charges, the company maintained a level system from 2009 to 2012 but may be still operating it to this day.
