While it's very satisfying to see the scammers being "pwned", unfortunately there's too little real life impact on the scammer market. They operate from poor regions where an overextended (possibly corrupt?) police force has little incentive or possibility to pursue such crimes. From their perspective they are essentially victimless crimes. The victims can't complain, they're are on the other side of the world, too far to matter when there are more pressing matters at home, and the fact that they can afford it lessens the moral burden of stopping the crime.
