Really? Because i'm fairly sure you've done as equal and have no right to talk. I will say again, not be offensive, and not get offended. Simple. You should be able to curse without it even being a FRAGMENT of an idea to imply a punishment. It's indomitably a corrupted system of which does BAN for silly, ridiculous things. People will report for anything nowadays, and if it does pass in tribunal, the case probably wasn't that extreme in the first place, it was most likely just a little argument, and some pissy whiny kid like you probably reported them both because you couldn't either respond and try and break up the petty argument, or you reported them because you couldn't be mature enough to let them have their fight. Yeah, players shouldn't be *******s to eachother, but they are, and when someone says **** to you in the real world OR online, they deserve to get a rain of hellfire upon them. It's a natural human right, rather it be online or not. You be nice to me, i'll be nice to you. You say **** to me, i'm going to call you out on it.
You and me obviously have different views of human rights, whether this is due to upbringing or education level, it doesn't matter.
Riot has taken it's stance on what type of chat they don't want to have in their game, they have that right. Just as you have the right to not play the game.
As many would say, "if you don't like the rules of this establishment, get out".
