For all of you who have been permabanned, just make a new account already.
Some of you might say " I quit this game!" but the chances are that quitting will not make you happy. The fact that you were frustrated enough about your ban to make a post and complain about it here shows that you will most likely miss this game if you quit.
The truth is that you actually still wan't to play this game.
I wrote a guide about leveling up your account very fast. It should only take you about 5-minutes to read this guide. If you follow my advice in the guide, you should have your account up to level 30 within a week. Then you can do your ranked placements again. http://www.lolking.net/guides/392167/preview
Everything described in the guide is okay, and won't get you banned. Buying a new account will get you banned.
Also, playing without runes isn't as bad you think. The most important thing you still have is your game knowledge, experience and skill. Riot can take all your runes, champions, and skins but they can't take away your game knowledge.
