Nigerian dating site scam
Some scammers have accomplices in the United States and abroad that move in to finish the deal once the initial contact has been made.
According to the Federal Bureau of Investigation(FBI), "An advance fee scheme occurs when the victim pays money to someone in anticipation of receiving something of greater value—such as a loan, contract, investment, or gift—and then receives little or nothing in return." The scam has been used with fax and traditional mail, and is now prevalent in online communications like emails.
One variant of the scam may date back to the 18th or 19th centuries, as a very similar letter, entitled "The Letter from Jerusalem", is seen in the memoirs of Eugène François Vidocq, a former French criminal and private investigator. One of these, sent via postal mail, was addressed to a woman's husband, and inquired about his health.
Another variant of the scam, dating back to circa 1830, appears very similar to what is passed via email today: "Sir, you will doubtlessly be astonished to be receiving a letter from a person unknown to you, who is about to ask a favour from you...", and goes on to talk of a casket containing 16,000 francs in gold and the diamonds of a late marchioness. It then asked what to do with profits from a .6 million investment, and ended with a telephone number.
More delays and additional costs are added, always keeping the promise of an imminent large transfer alive, convincing the victim that the money the victim is currently paying is covered several times over by the payoff.
The implication that these payments will be used for "white-collar" crime such as bribery, and even that the money they are being promised is being stolen from a government or royal/wealthy family, often prevents the victim from telling others about the "transaction", as it would involve admitting that they intended to be complicit in an international crime.
In exchange for transferring the funds out of Nigeria, the recipient would keep 30% of the total.
