The latest permutation of the classic “Nigerian” scam (you know, oops! my silly assistant overpaid you with my fake cheque, can you pay the travel agent on my behalf) is here.
Just don’t even bother. You can report it to the police, but they can’t waste their time on stuff like this. You can have fun with this person and collect another fake cheque for your collection of fake cheque, sure, why not?
But under no circumstances should you actually pay this person or any of their associates any money!
