I don't have the slightest idea.
However, those are two separate topics. The fact that the porn they consume is created out of their country doesn't make them any better, even if the rape rate there is way lower (I believe that's probably the case). If you think the porn industry is a problem (and it probably is), they're contributing to it as consumers.
It reminds me to Denmark, where casinos and this kind of stuff are forbidden. What do they do? They have ferries that act as floating casinos. They just need to wait for a few minutes until they reach international waters and that's it, problem solved, their country is free of gambling sites.. how nice of them..
