@PatrickWSwayzeAbaddon is correct. I have seen this occasionally in the lower skill lobbies or low ranks of ranked. It’s almost always a kid, occasionally it’s a player who’s just starting.
When it comes to identifying them through your xbox.. Their parents often put heavy restrictions on who can contact them and communicate with them.
