Blackmail is an act of coercion using the threat of revealing or publicizing either substantially true or false information about a person or people unless certain demands are met. It is often damaging information, and may be revealed to family members or associates rather than to the general public. It may involve using threats of physical, mental or emotional harm, or of criminal prosecution, against the victim or someone close to the victim. It is normally carried out for personal gain, most commonly of position, money, or property. It is also used, sometimes by state agencies, to exert influence; this was a common Soviet practice, so much so that the term "kompromat", transliterated from Russian, is often used for compromising material used to exert control.
