To be fair, for a change they're not asking for an advance from you. Could be genuine, could be!
But, I too have just come into a large sum of money and to avoid paying stupid amounts of tax I need a nice NZ bank to put it in. And you Mr Kiwi_2005 I trust. Simply PM me with your bank account details, credit/debit card details including the last three on the reverse, mother's maiden name, your first pet's name, a memorable location, your godson's cousin's grandma's uncles mother-in-law's name. Oh, I don't really trust you, but I'd like to - to help me to trust you could you please send me a cheque for $100 and then I'll know you're serious. In return you can keep 10% of my unexpected windfall.
Me love you long time,
Herr-B
