I was playing with some clan mates the other day and we happened to play against some people who were not as friendly as we were. After the game 2 players began to follow us from lobby to lobby swearing and throwing insults. These can be frustrating to deal with but it is important not to loose your head. They want you to freak and and doing so only encourages their behavior. If this happens take a deep breath, mute them or if they continue to bother you report them and block all communications with them. Lashing out and yelling back will only make the clan look bad so, ignore them and play on!
