Hi there, thanks for replies. As far as I understood from all comments here, that my approach has to be changed. Suppose there is no way to block this sites in the net in Kazakhstan, except speaking to Kazaktelecom and convince them to do it. But there are only few products on the market in Russian language to block this sites. What I was thinking is to find some good IT people and write this type of programm on Russian and Kazakh languages (very simple) and then strat selling them for private needs.
