Has riot changed his policy towards permabanned accounts?

My account was permabanned yesterday for saying "trash" 3 times in all chat after recieving racist comments from a 5 man premade team, they were saying stuff like -Build the wall -I hate tacos -Gross ass mexican -you dont know how to play -ur so bad -ur trash -me no speak r%%%%% And theres more, after muted them they continued harassing me in the result screen they even sent me friend request and then blocked me and they after a while i recieve a system message saying, i was suspended and then when i relogged it says permabanned. Can Riot do me justice? I have spent a lot of money i cant afford to lose my account i even got all champs including Qiyana I was so hyped until this problem came up. I even submitted a ticket to Riot asking if they could reduce it to a Temporal suspension, because Im aware that you cant make the difference showing the same actions as the people who mistreat you so I accept my mistake and told Riot I will disable the /all chat and mute toxic teammates so I can be a positive experience in game with others showing sportsmanship.
