I always ask for 18 or older. Seems to work. I had one 13 yr old join. His voice was deeper than mine i couldnt believe it. He was mature and good i was shocked. I didnt even know his age until days later when we played again he told me. Great kid now we play all the time. Hes the only little kid ive met om xbox that i can tolerate tho. Most are exactly as you described. Then they wonder why the community hates them
