The word 'blackmailer' is used to describe a person who threatens to reveal something embarrassing, harmful or damaging about someone else, unless they are given money or something else of value. This is generally considered a criminal act, as it is a form of extortion. For example, if someone found out that their friend had cheated on an exam and threatened to tell the friend's teacher unless they were given money, that person would be considered a blackmailer.
