While you might be wise enough to delete or flag emails promising great wealth in far-flung countries, not everyone is so savvy to these scams.
To ensure these scammers have less time to prey on real people, New Zealand online safety organisation Netsafe has developed a tool called Re:scam.
To use Re:scam, recipients of these emails need to forward them to firstname.lastname@example.org. It'll continually reply to the scammer in question, until they stop replying. To avoid detection, Re:scam is able to assume multiple personas, while using humour and grammatical errors as a real human would.
