It's time for a Country Block Mod.
The Q&A at registration is no longer effective nor has it been for sometime now. After viewing a number of topics in the forums, the recommendations always require some kind manual daily follow up and maintenance.
A mod needs to developed to ban by county IP. It's possible, it can be done.
The question is, who will be the genius to come up with an easy to use mod that works with out having to do things like update the htaccsess because not everyone knows how to do that.
