They use psychological tricks to lure their victims in, use poetry and even gifts to get them under their spell, and then once you are there, will try to reach for your wallet, all the time declaring their "undying love" for you.
You or someone you know may be dating this person online right now. No matter how good they sound, things aren't what they appear to be.
It's the newest evolution of the Nigerian advance fee (419) scam.

He's hunting through chat rooms, dating sites and social networking sites searching for victims, looking to cash in on romance.
