So I recently checked my e-mail for the warning I got from riot.
No I wasn't suspended and I only need one more game for it to be lifted

I just don't want this to happen in the future or me or anyone else

From what I can see, I got my chat privileges limited because I had leavers on my team, and for trying to get people to pay attention.

1 game I was actually reported by my teammates, that game had a leaver
Second game was by some random enemy who didn't know what was happening in the team chat
Third game was reported by one teammate who told us in selection he wasn't going to help us, so he reported everyone on my team
And finally the fourth one was given yet again by an enemy player who didn't know what was happening in our team chat

first of all, games with leavers in them, should not allow other players but the leaver to be reported.
A leaver can cause great stress and cause normally fine players to yell a little.
Why the tribunal still exists I have no idea, not everyone gets banned for punished for no reason, but it does happen every now and then.

This happening to me recently pushed me to make this thread

In game 1, you were pissing off your own team enough that they felt like reporting you. Don't take your rage out on the rest of your team just because you had a leaver on the team. Yelling at them wont solve anything (caps implies yelling).

I laughed so hard reading this. First game is an aram game and you're chatting as if you were a shout caster. Then I saw this.

Annie [All] [00:26:02] BG
Kayle [All] [00:26:09] GG
Annie [All] [00:26:09] we had a leaver
Kayle [All] [00:26:12] so?
Annie [All] [00:26:13] kayle don't cry
Kayle [All] [00:26:19] ?

I wanna know why this was a warning and not an actual ban.

I'd wager that you got punished because you kept typing in all caps. I personally would have skipped your case because I'd be completely on the fence about it. On the one hand, it does seem like you're giving genuine advice and direction. On the other, the fact that it's almost entirely in caps just makes it look like you're yelling and being rude (I'm not saying you necessarily were, I'm just saying that's what's being conveyed). Sorry this happened, but it's only a warning. Take it to heart and lay off the shift key in the future.

wonderful, the forums are still filled with five year olds who think that all yelling is insatly someone raging.
Yell at your teammates doesn't have to be "raging", it can easily like in my case, be the player desperately trying to get the attention of their teammates because they refuse to stop doing one specific thing that is throwing the game.
