it wasn't just me flaming that riven was flaming at me all game for her diving and dieing early game and so did the team they over extended and told me to farm yet I got reported?
Every player is judged purely as an individual. Nothing anyone said to you effects if you get banned, and nothing you said to them effects if they got banned. Meaning, it doesn't matter if someone else broke the rules or not. If you break the rules you will be punished.
im not saying that you shouldn't punish me, but I feel that perma ban was a bit too far.
Punishments generally escaulte to the next tier:
- First Offense: 10 Game Chat Restriction
- Second Offense: 25 Game Chat Restriction
- Third Offense: Two Week Suspension
- Fourth Offense: Permanent Suspension
Yes, the chat logs you posted likely would only result in a chat restriction... at first. But if that chat restriction doesn't stop you from being toxic, you get a longer restriction. If that doesn't stop you, a ban, and if that doesn't stop you, you get permanently banned. Note that this system can decay over time (meaning if you get a 10 game chat restriction but then are perfectly fine for a long time, you may only get a 10 game chat restriction next time too), but that depends on if you are being toxic or not.
is there anything I can do or anyone in my situation to prove ourselves to get unbanned?
Unfortunately no, I'm afraid not. The 14-day ban is considered the final warning. It is one last attempt to improve your behavior before they determine reform is too unlikely. You can make another account though, and if you are truly reformed then that account shouldn't get any bans. It sucks to lose that many skins, but that is the price of toxicity.
