Game #1 - No idea. Enemy spite report it looks like.
Game #2 - Dick to Wukong who you obviously didn't like - Enemy (?) reported you. No idea.
Game #3 - Annnd this might be why you're banned. Constant abuse of your team AND the enemy team in all chat. Trash, pathetic, dont play again, blah blah blah. Actually surprised only one person reported you, since you were a dick to everyone.
Game #4 - You harass udyr, threaten to afk and say "I'm done". Again, more ranting and raving.
Game #5 - More ranting, more raving - not as bad as game #3-4 though.
Not sure what I would've done here. Game 1-2 were literally nothing, Games 3-4 were pretty damn bad. Game 5 was meh.
Could've gone either way, but I think community would've read Game 3 and punished it hard.
