Dr. Mehmet Oz, the celebrity surgeon and television host, recently co-authored an op-ed piece for The Wall Street Journal addressing the proliferation of false celebrity ads on Facebook and how these ads are deceiving consumers and harming the reputation of the celebrities involved. Dr. Oz is not the only celebrity facing this issue. Others include Kelly Ripa, Denzel Washington, Bill Gates, Barbara Corcoran, and Will Ferrell, to name a few.
