It sounds great to add an extra badge to the number of badges on Discord and have everyone have access to it.
It would be great if it would appear on the discord profile to indicate which country the users are from.
I'll tell you why I did it to the badge, the number of badges on Discord is too small for everyone to access. So if this system is on the badge, it really adds style to the profile. It can also be done in the opening part of the Discord account, but my preference is to display it in the badge part.
Users who wish may/may not display the badge on their discord profile, who may change their current country to another country, but a warning will appear that you cannot change it until after the change after 60 days or a different period of time, and so on.
