Has been around for quite some time now.
Yes, but people are STILL being sucked in by it!
I've been keeping the scammer on the line and corresponding with him to see which avenue he's trying to take with me. He even has a valid phone number and answers with the company name etc. Quite an elaborate set-up. He's probably using a Skype phone number as you can have a phone number in any country these days and still be based in Nigeria
