There was a case where a famous actor was blackmailed. A person claimed to have some compromising photos of the actor from a private party. The actor, instead of succumbing to the blackmail, held a press conference and admitted his mistake of being in an inappropriate situation at the party. This transparency made the public support him, and the blackmailer was shamed and stopped the blackmail attempt.
One story is about a businessman who was blackmailed by an employee. The employee found some unethical accounting records of the boss. But instead of reporting it properly, he tried to blackmail the boss for a large sum of money. Eventually, the boss reported the blackmail attempt to the police, and the employee got into big trouble.
