Let's ban negative words
The current tribunal looks for a set of words defined by Riot after you have been reported by a player. This player could have thought you were out of line. This player could be acting out of spite because they lost a video game, the automatic tribunal is not able to determine this. This set of words has never been brought to your attention but you will be punished if you use one of the words and are reported by either of the aforementioned players or any player in between that spectrum.
If this automated system finds a word that you've used along with a report from another player it will eventually punish you.
This system is assuming that you will never run into a player who is spiteful. It is assuming that every time you are insulted by a player under ANY circumstances and use a word on their list that you are a negative toxic player, because you can be about %70-%90 sure (based on my personal experiences) that if somebody insults you, they are going to report you bump that up to %100 if you respond to them with a single word.
Instead how about we have a chat filter that is automatically on at all times. This filter will restrict this list of bad words and punish anybody that uses them, and we can just add to the list of words as a community. We can add words like 'stupid', 'bad', 'uninstall', 'suck', 'vaginal discharge' and anything else that anybody in the entire world could potentially find offensive. Nobody will ever say anything bad in league again and we can all live happily ever after.
P.S. GG Riot for employing the person that designed this system and then actually implementing it.
