So I did a lot too much research and went through all the posts from the African countries that I could find country codes for:
-Excluding yours, there are 19 posts from Africa 1 from Libya, 17 from South Africa and 1 from Tunisia
-Some probably use Vpns -you can notice some people's flags changing in between posts.
So you probably aren't the only one but I was surprised to see most of the flags completely empty
