Africa is a continent with over 50 countries. That is like saying, why don't South Americans stop drug cartels? "Africa" isn't a specific government. There is a good chance that some of the governments don't even know about the cyber-fraud that's happening in their country. I'm sure that some of the countries are fighting against it. If you take Nigeria, for example, they have over 190 million people. I'm sure, if there is a real fight with cyber-fraud, it's extremely hard to keep on top of with so many people. As far as I understand, the biggest problem is that it is very hard to track where the cyber-fraud is coming from.
