KYS is a reportable offence.
So i had this game where opposing team won. Nothing new....instead of showing honorable sportmenship, this opposing yasuo went cocky and act like he's a pro. But even pro players shows respect to others. He then typed kys during the end-game score chat before he left. I just hope he will get punished for that. If he ever act that in a public places, I'm pretty sure he will be smacked down on the ground immediately instead of hiding behind his PC, acting cocky and tough.
