Blackmail is a crime where someone threatens to reveal damaging information about another person unless they receive something of value, such as money or favors. This coercive tactic exploits fear and vulnerability, often causing significant emotional distress to the victim. The information used in blackmail can vary widely, including personal secrets, embarrassing photos, or illegal activities. Victims may feel trapped, as complying with the demands does not guarantee that the blackmailer will keep their word. Legal consequences for blackmail can be severe, as it is considered a form of extortion.
