Even before his trial, Ponzi's name had begun to pass into the language as a fraudster. This 25 September 1920 ad for Washington Mutual Savings Bank in Seattle, declares, "Don't Be Ponzied".
A charlatan is a person practicing quackery or a similar confidence trick in order to obtain money, power, fame, or other advantages through pretense or deception. One example of a charlatan appears in the Canterbury Tales story "The Pardoner's Tale," with the Pardoner who tricks sinners into buying fake religious relics. Synonyms for charlatan include shyster, quack, or faker. Quack is a reference to quackery or the practice of dubious medicine, including the sale of snake oil, or a person who does not have medical training who purports to provide medical services.
