Unjustfully Chat Banned

I'm going to start with the premise that i'm not the perfect player. I've been toxic before and have actually been working hard to reform and had just hit honor level 1 a few days ago, after a few months (highly motivated because missed out on clash due to low honor levels).

Now onto a little background information about the game: our Yi had successfully secured the early game, racking up 9/0 pretty quickly. I was struggling top lane as Quinn against AP Malphite, and had repeatedly asked for ganks from the team (see chat logs) Yi came top once. Quelle surprise that I end up 0/4 as the bronze 1 player that I am against a hard counter and (wow!) team starts to flame.

Alright, that's fine, I release a string of words explaining that his q poke literally does 250 out of my 1100 health (nothing too insulting or strongly worded) to defend myself and move on. Fine.

This is when Yi starts to power farm for the rest of the entire game. He would move from camp to camp, doing nothing in team fights and we would end up destroying nexus without him and I as the Quinn pulling back from a 0/4 laning phase. Honestly, it was like playing with an AFK. Team called multiple times for him to be present in fights, met with "XD" and "You suck" (or something along that line).

Either way, we had to fight a 4v5 battle and it was hard.

Understandably, at the end of the game i'm not the only one calling for reports of afk farming and griefing, and multiple times at that to make sure it sinks in and he gets some form of repercussion for his terrible behaviour in game, but it seems otherwise.

I've downloaded the replay but can't play it (it's a .rofl file?). If anyone at Riot is seeing this, please review the game footage from this match: https://matchhistory.na.leagueoflegends.com/en/#match-details/NA1/2825432501/241246501?tab=overview

And chat logs from Yi when asked by Ornn to come help the team.

TL;DR: Yi does nothing for the rest of the game after acquiring 9/0 kills and power farms while we team fight and while enemy is cracking open base. He has a combined total of 8k champ damage. That is not ok. Calls for Yi to be reported due to this. Gets chat banned.

Edit: Also just realised that Yi had 0.0k turret damage, to illustrate my point further of an afk player. [zombie-brand-mindblown]

ALSO LET ME MAKE IT CLEAR.

I am in no way justifying my words and actions in ANY OTHER GIVEN SITUATION. Just this SPECIFIC situation in which the Yi was power farming his heart out, which statistics show as well, I am trying to justify.
