I don't know about that, I just think it's cool for people to use VPNs to spy on what is happening at the other countries.

You could generate some interesting statistics looking at the country’s data individually.
A way to disable VPNs was not developed for that purpose I guess. Anyways, there could be situations when it’s necessary to block using VPNs so it’s better to develop it as a backup plan, don’t you think?!
