People should never be judged on what country they are from, but what they do. This idea will not solve anything and it is also illegal.
It's illegal if they're banning an entire race of people (don't know how'd they do that through a game). Banning a country would just be like a tariff or something, not really illegal.
Tbh Australian officials at airports got in trouble for profiling people from Nigeria as drug traffickers. Both races from Nigeria, black and Asian, were being detained.
But were they actually drug traffickers? The reasons why the Israeli's profile people is because it works.
Well obviously the vast majority weren't; which is where the problem lied. And by targeting these people they started ignoring other groups with some among them being drug traffickers. This pseudo-racial profiling phase must have been a dream come true for drug traffickers from countries other than Nigeria.
