I feel like it would be cool (and easier) if you were able to filter leaderboards by countries (only the ones in which the category has runs for).

You can request this in support hub But this would be a cool feature

@Ridgy Why would the staff make this happen. There are 195 countries in the world, and we don't want to take our chances in filtering out that one guy from North Korea.

There are actually 197

I found a few websites. Each of them say different things. For example, there are 193, 195, 197, and even 215 countries in the world

This used to be a filter (kind of), but they took this away when they removed the statistics page
