The Nigerian Scam gets even better. I received an invitation to attend the "2nd International NGO/CBO Workshop". Sounded great, all expenses paid trip to New York for up to 4 members of my organisation. Funded by the real Jacobson Foundation, and in part by the Bill Gates Foundation, and the invite was a 'glossy' PDF brochure. Only catch was, to attend you had to Western Union $300 per person to a post office in West Africa....
If they'd have had you wire the money to the US it would have been perfect. I know of a case locally where a whole group were invited to West Africa only to get there to find it was a scam. Our Government even contributed air fares. At least the group got to see Africa.
But like I did with this scam, Google the event. If there's not a whiff of the event, take a closer look. Especially given it was supposed to be the 2nd of its kind, why nothing online about the 1st?!
ALERT: watch out also for the 'Forum on Human and Community Development Financing'!
