The Nigerian dating scams are often not easy to detect as the scammers are often highly educated, have exceptional patience and they do their homework!
The scammers start by stealing a photo from an internet site.
They also tend to target middle-aged people looking for stable relationships.
The scammers choose chat rooms and dating sites because the person in love offers the chance of the biggest payoffs.
The photos are usually stolen from modeling sites with reports that 90% of them are being taken from Focus Hawaii.
If you think you are being scammed, go to this site and browse all the photos to see if the person you are communicating has a photo on this site. However they also use photos taken from profiles of other people on dating sites, so remember that the photos that scammers use are not photos of themselves - they are photos of innocent victims.
They then spend months chatting up and luring their naive targets with online intimacy.
They often pretend to be foreign specialists [from the US, UK or Canada, but can be any European country]temporarily working in Nigeria or other African country.
