Don’t pretend like you’d read such a list. You just said you had no way to figure out why a country would be banned from an international competition just one comment ago. If you couldn’t even think of reading an official explanation, we’re supposed to believe that a list that would be published in the same place would result in you being better informed?

It’s pretty dead simple to ban a country from competition for being warmongering and genocidal. What would be complicated?
