There are some websites that have taken the fight to these mugu scamsters www.419eater.com and www.419fun.com for example. These people have their own books and they also help unmask and post pictures of scamsters and their assciates on the net.
On the other hand, it is sad that the Government of India does little to alert Indians of these frauds unlike the Brotosh Government and the FBI in the US who have an elaborate procedure for dealing with these criminals. Nigeria is a den of thieves and the world needs to wake up to these criminals and their scamming ways.
