Very good tips. I'm actually a member at 419eater and have screwed up a few scammers! (who incidentally are not all Nigerian), There are many many scammers all over the world. Personally I have dealt with Russians and Filipinos (dating scammers) Malaysians and Chinese (advance fee fraud) (fake electronics sales) and the Classics from Africa, Ghana, Burkino Faso, Senegal, Benin, Ivory Coast, Mauritania and of course Nigeria. I also have a favourite from Azerbaijan who tried to sell me a 1500kg diamond. Yup 1500kg!! he was also able to get me Mithril and Adamantite! (Made up metals used in fantasy stories, games & films)
anyway 419eater has a new site which I would recommend for further reading into scams
Stay Safe and stay away from orphans in non-existant refugee camps in Senegal!
(one of the most common scams to hit dating sites)
