Facebook users are spreading a message claiming that Bill Gates will cough up $5000 if you share a photograph of him. The photograph shows Bill Gates, holding a piece of paper which appears to contain the following words: ‘Hey Facebook, As you some of you may know, Im Bill Gates. If you click the share link, I will give you $5000. Its about time I give back to the people!’ The genuine image, which the hoax picture is based upon, was used by Bill Gates to verify his identity on Reddit.”]
