I have a Proxy site which got very high traffic once created, I advertised for it but this traffic made me spend more money for my hosting I also noticed there are some countries how are not cost effective so they take a lot of bandwidth and will get you low money these countries are : Saudi Arabia Iran Kuwait and some other Arab countries that its because proxy users from these countries usually use it for sex and porn and spend lot of times on the other hand users from US and Europe usually go to facebook or youtube .... so I creat .htaccess file to block users from Saudi Arabia , Iran and Kuwait use this code in it <Limit GET HEAD POST> order allow,deny deny from 62.3.0.0/19 deny from 62.3.32.0/19 deny from 62.149.64.0/18 deny from 77.64.0.0/17 deny from 77.73.192.0/21 deny
