Scam
attempt to defraud a person or group after first gaining their confidence / From Wikipedia, the free encyclopedia
A scam is a kind of fraud. It works by first gaining the trust of the victims, and then either asking them for money, or other things, or asking them to commit fraud. For this reson, scams are also known as confidence tricks. Researchers have defined confidence tricks as "a distinctive species of fraudulent conduct ... intending to further voluntary exchanges that are not mutually beneficial", as they "benefit con operators ('con men') at the expense of their victims (the 'marks')".[1]
