Armed with their fake identity, the scammer proceeds to forge a bond with you.They often communicate with you for weeks and months so you think you are getting to know them better while it is actually all part of their master plan.
Similar to the Spanish prisoner scam where the scamster promises to share his fortunes with the victim in exchange for money to bribe the prison guards, the Nigerian 419 has fully come into its own thanks to the availability of email.
A scam victim will usually receive an email making an offer of a large sum of money.
This breed of scams has been around for a very long time and is known as the advance fee fraud.
It has various names such as the Nigerian 419, Nigerian money offer, the Spanish prisoner etc.
Once you do send the money however, it is unlikely that the visit will ever actually materialize.
