Quite an innovative way to combat phishing fraudsters. 

New Zealand have developed a bot which finds fraudsters and engages them in endlessly long email exchanges. The idea is that this keeps them away from real victims and it allows authorities to garner information on these criminals.  

Time will tell if it is successful but it has the feel of a "sticking plaster" approach to me.  

Also, have a read of the conversations. Do they seem authentic to you?
