Unjustified Perma Ban

Alright, so as the thread states, a while ago I got a permanent ban on LoL. And honestly, I never got why. Yes, I was showing bad behavior somewhat. I mean, if you are trying your best to win, and your jungler starts taxing and failing ganks, its not too surprising one gets upset. But I never used vulgar language. While an punishment is justified, in this case a chat restriction would have been more than enough. My biggest offense was just simply saying too much. Putting a muzzle on my mouth would have shut me up, and made me re-focus. I was also just back again at honor level 3, I was consistently reforming from issues way in the past. So here is the chat log. Now I wonder, do you guys really think a permanent ban was justified over a chat restriction?
