They're perfect. In fact, they're someone you could see yourself spending the rest of your life with. A decent person with a good job or business in search of a good, honest partner to settle down with.
They use psychological tricks to lure their victims in, use poetry and even gifts to get them under their spell, then once you are there, will try to reach for your wallet, all the time declaring their "undying love" for you. The scam may take the form of asking you to cash a cheque for them through your bank account because they are "out of the country" and unable to cash it themselves, or they may come right out and ask you to send money to help them out of a fabricated "financial difficulty" they claim to be experiencing. These are all lies used to try to make them easy money from an unsuspecting victim.
The sad truth is, for every real profile you see on the internet, there are numerous false ones pretending to be your perfect mate and using photographs stolen from modelling or social networking sites. The people in the photographs are as much victims as the people who get scammed for hundreds, thousands, even tens of thousands of dollars. Internet romance scams and other related crimes are very real, and they are affecting, even ruining, lives throughout the world.
