Can a user be blocked on Google play store in an android app?

I am seeing this app "Peshawar Police" is not available to me and when I go to it via link, it says "not available in your country". I have verified other users can access it and download it. My question is, is it possible to block user on a particular App and doesn't that violate privacy that you hunt for a user and block him from accessing g thr app? Screenshot attached. Additionally why the message is misleading? Just a polite way to deny you access?
