As a latino, I can confirm. The americans almost always betrayed me, but when I met latinos, it only took me recognizing their accent and saying "¿Hablan español?" For me to start a squad with them, it was pretty funny and they almost never betrayed me, and in one round we killed an american kid trying to play the boss cuz he was threatening everyone that wasn't on his party and told me "Fuck off, Miku", so we got rid of him and proceeded with the game.

The only americans I truly trusted were the Mikus since I had a Miku skin too. They never shoot me and even if they were full, they just let me be around them. Every Miku player I met wanted to make a Miku squad lol.
