Reminder that if you win a game...
That it isn't automatically a free pass to be toxic. The summoners code states:
4. ENJOY YOURSELF, BUT NOT AT ANYONE ELSE'S EXPENSE and 6. SHOW HUMILITY IN VICTORY, AND GRACE IN DEFEAT
Too often is the "losing" side of League linked to the well known toxic problem in the community, but to say that the ONLY people who are toxic are the people having a bad time quite frankly isn't right, and it promotes the idea that because toxic-victory isnt talked about, that it must be acceptable. And this is far from the truth. We can't rid or even begin to prevent the toxicity in the League of Legends community if the perpetrators of this divisive toxic behaviour are not only those who are on the raw end of the game, but also the ones who are victorious.
Remember that even though there are winners in your game, that there are still losers, and they (potentially) won't be enjoying their time as much as you are, so there is no need to show them what they already know by putting them down any further!
Do the right thing, and don't taunt people and become part of the problem
