I totally agree with your point. Blocking this certificate in major browsers or warning users would be of great use.

But there is a minor remark I have to make here. I'm sure you were talking about citizens of Kazakhstan, when you used the word "Kazakhs". The word "Kazakh" actually denotes an ethnicity, not a citizenship. And although Kazakhs are predominant ethnicity in Kazakhstan (~65% of the population), there are many others, and it's incorrect to call them Kazakhs.

Wikipedia suggests "Kazakhstani" as a English term for Kazakhstan citizens. I also saw other people using the word "Kazakhstanians". Maybe one of these two would be a better choice than "Kazakhs".
