Permaban?

Before anything, I agree that my account is my responsibility. I recently handed my account to someone else (let us call him qazw) because they were on another server. Qazw was a little aggressive and during one game, he went full-off. Well, he was adc and flamed the support who was 'intentionally feeding' (0/4/1). And I agree that he shouldn't have flamed but the worst thing he called the support was "braindead". He spammed that. But it's nothing like the chats I see today who don't even get some sort of restriction. I recently played against someone who was constantly being Islamphobic and racist "Oh im white. Go muslim die. F--k Muslims. %%%s. Can't ban, I'm white" sort of remarks. I did mute and report them but obviously, riot didn't do anything. How can "braindead" be perma-banned but not something like this. My account, when I was on it, usually got honors every single time. The honors outweigh the flaming by a lot. Shouldn't they considered this too? I've gotten loads of honors all throughout when I played. Is there anything I could do to get my account back? I know, permabans don't get taken back. But is it possible to consider all the honors and outweigh the ban? And to check once again if there is any other history of my account flaming at someone? I'm pretty sure "braindead"/"f--king useless support"/"don't play braum" doesn't deserve permaban. There were no threats towards the person himself- just the way they were playing, and no racist/homophobic remarks.

Thank you and kind regards, A
