My Problem: I own a proxy site. One day I log into my Cpanel and notice that my bandwidth shot up almost 200% in 6 hours. Wrong, my site was being abused from people in Iran, chewing up my bandwidth. I checked adsense and saw that my clicks had jumped, but the quality of the clicks wasn't good, because the ads arn't relevent to Iranians. I needed a fast fix, I thought blocking them with IP ranges in .htaccess was the best way. I found Iran has about 200 diffrent ranges, after doing about 20 ranges, I figured it was too slow. I went searching for another solution. The Solution: http://lonewolf-online.net/computers/knowledgebase/php_block_country_from_accessing_website/ It explains step by step what to do. I also changed the error page that I made specifically to Iran to contain many pop ups and unders. That way they can pay back what they spent. I drasticly decreased my bandwidth, got rid of trashy traffic, and increased my revenue
