Google paid a $500 million settlement to U.S government for showing ads from illegal online pharmacies. The reason is that Google was showing those ads in their knowledge and U.G government proved that with the help of a con artist. David Whitaker, the con artist sent by the government, appeared to Google sales executives as an agent for (illegal) online drug dealers. He spent about $200.000 (government’s money) in paid ads for selling illegal drugs. The website he created was very obvious to Google that it was not a licensed pharmacy but they accepted it (in order to make money). You can read the full story in the source link. Google now in not the Google we knew back then and they no longer follow their do no evil policy.
