I don't think Admins are gonna block Brazil as a whole, you don't have to worry about that.
I don't like people who play who can't understand English at all, but if they would block whole of Brazil you can bet money I'll be among the crowd that's gonna make even more fuss about it than people that make fuss about BR.
You may see messages in Discord targeting Brazil as a whole, but those are either assholes, trolls or some people are just joking a bit.
I think you don't have to worry about anything just because you're from Brazil.
As is stated by you and other people. Report rule breakers and everything should fall in place.
P.S. I am also to blame, because I make a fuss, but don't report and I apologise for that. That's why I don't talk much at all lately.
