League of Legends NA just banning people for verbal abuse without looking at the game.

Well League of Legends NA has frequently banned my account due to verbal abuse as well as negative attitude. But the thing is, they never review the games that I verbally abuse other players. Having a troll teammate and a intentional feeder doesn't make you get mad? When you have won 19 of your last 20 ranked games and RIOT NA just banning players??? FOR REAL? Why can't NA people monitor the game plays not just the chats. That's how you improve your community. By getting rid of trolls and players who just want to mess around with you during ranked games. And players who actually wants to play for real and to improve their game play, and people who play seriously. To some people ranked games might be a joke. But for others it isn't. Making 30 to 60 minute every day to play a single ranked game. And having trolls in your games? Is that even fair? Why don't you LEARN something from RIOT KOREA where they have the best League of Legends Team in the world. Korean servers insults your mother, your parents, grandparents, and even about your pet dog. And you know what. I never got banned in KOREA. This is because people in Korea play seriously. That's why they have the better players. Korean bronze and silvers are equal to platinum in NA. This is all because RIOT KOREA let's player play competitively and letting players to use verbal abuse as a way to motivate. BUt here in NA there is nothing like that. This is because people don't care about winning ranked games. All they want is to play whatever they want and just ruin the game for serious players. RIOT NA what a shame. Is that why NON- ASIAN countries are all bad at League of Legends? Cause apparently every other servers, you guys care, but not KOREA where KOREA has its own League of Legends.
