literally trolling rumble in team

So heres what happened. He locked in rumble without playing the champion in the past 30 days (counterpicked himself) When he died the first time he started flaming n stuff After he died like 3 times he decided not to go top and start griefing other lanes (he came botlane took like 4 minion waves before he went to midlane and did the same) by the time he really decided to start hard griefing was when he had 6 deaths and a kill. kata said "we could win" but instead of trying to he just griefs even harder by inting and saying " i won't let you" He also said that he'd troll if we were close to inting if im not mistaken.

I'm sorry for my bad english.

please get this guy banned.
