Negative Game Play

I feel if we couldn't literally reduce the negative attitude such as verbal abuse, no one really wants to play this game anymore. Tonight I played with a person who intentionally feeding during the first game, verbal abuse during the second game, and finally choose to AFK during the third one. I found out it was so hard to tolerant such behaviors as we all play and enjoy this game for fun. I feel there isn't any point to play in such horrible gaming environments...
