You can meet a lot of those guys in kindergartens. Did you hear saying about stupid people and falling to their level then losing to their experience? Just ignore the **bleep**, report with description "harassing, offensive language" and be done with them. The more interactions with them you have the more their brains get damaged and the more unbearable they will be. There will always be those kind of kids in any multiplayer game at any rank :/
Edit: lol that censoring is wild. i feel like ea is trying to go into snowflake area, yikes.
