The Nigeriandating scams target the lonely and vulnerable.
The most common comment of victims who think they have found the love of their life is "I can't believe I was so stupid!
Some of the sophisticated scammers send cheap presents such as flowers or candy [from stolen credit cards] to capture the hearts of lonely women. They either advise that their employer pays them with Money Orders and they can't cash them in Nigeria or are having trouble cashing them.
Then they convince their soul mates to bank them into their bank account and then wire them the money via Western Union.
They ask if their soul mate can re-ship them to Nigeria.
