Have you seen Sololearn profiles without a country? I first thought these were bots but some seem to be actual people/learners. Why is the country setting optional in your profile? In fact, I think anyone can even enter a random country which is not his/her own. Why does Sololearn not use an IP address or geolocation to cross-check or automatically set the country? I understand privacy may be important to some but is it OK to be able to fake your country, even if geographical borders are not so important in a global future?
