High Quality Content by WIKIPEDIA articles! Scam baiting is a form of Internet vigilantism, where the vigilante poses as a potential victim to the scammer in order to waste their time and resources, gather information that will be of use to authorities, and publicly expose the scammer.

It is primarily used to thwart the Advance-fee fraud scam and can be done out of a sense of civic duty, as a form of amusement, or both.
