Thank you riot ^^

I sincerely thank you riot for giving me another ban. So instead of fixing your game you intend to fill it with more stuff and release new champs. I did afk once or twice before I get this ban but it was in bot. I was in a ranked game and everything was alright untill champ select was over and we went to the game. And that's it black screen. I tried restarting the game reconnecting but nothing until finaly that message pops up : for the recent bla bla. Can you explain that to me please ? What caused this ? ps: my brother was also playing at the same time and connexion was working fine (90ms)
