Why is this guy not banned, but I am ?

First of all, I would like people to read my thread below. http://boards.euw.leagueoflegends.com/en/c/player-behaviour-en/R38m0mhn-banned-for-literally-no-reason-riot-embassys-mods-admins-please-read?comment=000300000000 Now, I have created this thread many times and been ignored. I keep getting banned and getting sent mildchat logs, sometimes I can understand the ban, but in the above thread? No way. That's compeltely unfair. A riot embassy told me the reason I was banned was because It was " my fault , i encouraged a negative atmosphere by 'aruging' with the people flaming t me, therefore I am responsible for them flaming at me.. tl;dr if you don't want to read the thread - they all flamed at me for playing badly, I was askign them things like " what did I do " " wtf i did nothing wrong why are you reporting me " and I was banned. This apparently is ban enough for a permaban as it's my fault because im 'encouraging' them to flame at me. Now onto THIS read. My friend, who recently was permenantly banned recently rejoined and hit level 30. I have been playing with him alot recently. He has been doing the below screenshots for weeks now and he has not recieved a chat rstriction yet. I know for a FACT people report him, including me and my other premade friend. http://prntscr.com/awvvu9 http://prntscr.com/awvvzj http://prntscr.com/awvw7i http://prntscr.com/awvweo http://prntscr.com/awvwij http://prntscr.com/awvwl4 Aswell as the below screenshots, he spams " %%%%%% " " coon " " fuck you %%%%s " " report x person " trolls / runs down mid " i hope isis kill your family " etc, you get the point. The above 2 screenshots are of our games today, yet he's been doing this for weeks. now, can someone explain WHY HE'S NOT EVEN CHAT RESTRICTED AND I'M PERMENANTLY BANNED BECAUSE I WAS ASKING PEOPLE WHY THEY WERE FLAMING ME?** Nope! None of you can. Why ? Because tribunal is ridiculous and bans for ridiculosu reasons. Thanks, riot.
