If you go to "Community" on the menu at the top of the screen and select "Members List" and then "Search Members" on the right side of the screen (roughly in the middle) and then select "Advanced Search", you will be able to get close to what you are looking for.
Enter "0" in the field "is Greater than or Equal to" and select a Country from the drop down list. For example, when I select Sweden, I get 68 TF members -- most have not posted anything. So, unfortunately, you have to do this country by country. I haven't managed to find any workaround to get the whole list where it shows country.
I found it interesting to see that in the whole of TF, about 14,000 members have never made any posts!
Good luck!
