If you don't want your profile to be viewed by users from certain countries, you can add those countries to the list of "Banned Countries":
1. open Account Settings and scroll down to Banned Countries;
2. click / tap on the input field and either search by scrolling through the list or start typying the country's name and then click on it when it appears;
3. click / tap Save;
When a user from a blocked country tries to open your profile page, they will see that the account is unavailable.
