Hi Berri Bunny,
It's pretty clear to the community that you were trolling in that game.
Completely refusing to communicate with your team in champ select, and then insta-locked a very unusual jungle champion when your team already had a jungler chosen.
You might have a sliver of sympathy if this was a rare occurance, but a quick look at your report history indicates that you do this often.
Quite often in fact.
Your numerous other offenses include verbally harassing others, refusing to play with your team when you don't get your way, and giving up when your surrender vote fails and just farming non-stop to cause your team to lose.
As I we have frequently mention in the past, it takes many reports, from many games to even be considered for the tribunal. In your case, you've been reported in over 20% of the games you've played in the last 30 days.
20%... the average League of Legends player is reported in less than 1% of the games they play.
From a Riot perspective it's pretty clear to us that the Tribunal worked as intended in this case and that removing you from the game was a wise choice. What happens next is up to you.
You'll have two weeks to reflect on your past actions and even change your behaviors so that you never have to end up in the Tribunal again.
Or you can stubbornly refuse to accept the truth put before you and end up with a permanent suspension.
I wish you the best of luck.
