Alright so let me explain something about bait banners and why you're really getting yourself banned overall...
- Nobody can make you act outside the rules
I know this seems simple but the thing is you were willing to act outside the acceptable use of the chatbox. It is meant to progress the game in your team's favor by relaying information or congratulating good play to encourgae a team member. You chose to respond to someone else who was outside the intended purpose then you went outside the rules.
- The things that result in immediate ban
The things that result in immediate bans are all things that common sense dictates you should not say. Zero tolerance things such as racist/homophobic speech or calling for somebody to end their own life are all clearly not acceptable.
- Them setting a win condition
If they set a win condition based upon you acting outside the rules then it is your decision that leads to you acting outside the rules and conducting yourself in a ban worthy manner. You know what is and is not acceptable behavior. The summoner's code is not some obscure thing you cannot find. You can easily look it up and follow the simple guidelines to not be banned. Nobody has ever been banned and remain banned for following the summoner's code.
- You reacted in rage but were baited in to raging
Again this comes down to personal accountability. You chose to react in an unacceptable manner. Nobody can make you do anything on a video game.
Basically with these things in mind that's why i do not believe that anyone who is "bait banned" should be unbanned. You chose to act outside the rules whether prompted or not. Your decisions were something you made and must now deal with the consequences of. You do not deserve sympathy for some boogeyman who magically made you say racist/homophobic things. You need to reevaluate your outlook and decisions if you are banned and decide how you will be above repeating that behavior thus the idea of being "reformed". Being "reformed" is owning up to your actions and accepting accountability for them. Then realizing they are not good and changing those habits for the better. So do yourself a favor and accept the blame for your actions and know that you can simply mute these so called "bait banners" and choose to not break the rules.
TL;DR : Nobody can make you do anything. You are accountable for your actions including chat messages . Nobody else's actions modify how the rules apply to you. Fix your behavior and you will not be banned for reacting to minimal prompting for zero tolerance triggers.
