Please tell me. I am constantly seeing those spoiled brat who only quit for minor things.
If you are on XBOX, go to your menu and then to the previously met players tab on the far right hand side and find the user. Now press on their name and go to 'Summit a Player Review' and choose Avoid Player.
You will now avoid this player as often as possible, so there is next to no chance you will meet them in public lobbies on ANY game.
PSN, add them to blocklist, if it is full just put them on mute when in the lobby, next time they join your lobby you will see that you have muted them in the past.
