Thanks for the kind words!
It's nice to know when others are helped by such simple advice.
You can block counties for free in the .htaccess file and there are lots of sites out there that give you cut & paste code to drop in so you don't have to know much except how to edit a file to make it work.
My experience with blocking some abusive countries was a huge initial spike in AdSense but it then dropped again and leveled off, but it leveled off higher than previously because I no longer had all the junk traffic.
Google tells you not to block people from accessing your website but they also penalize you for doing it and don't penalize those that rip you off and often reward them better than your own site!
Makes no sense whatsoever.
