Riot and the regulation of language.
Restricting and regulating the words and language used in League of Legends is hurtful for the community and for the actual people oppressed by matters of which the words are meant to represent. Words like n**** are not used for establishing or labeling people of African American descent in League of legends. Nor is anyone in League of Legends (Of my knowledge) oppressed by this. Words do not have the meaning of which the media has labeled it. same goes for words like fk. It has nothing to do with sexual intercourse of any sort. And nobody believes it has. This is why, when the general public says "FC" out loud, nobody pretends to take the literal meaning of the word serious. Same goes with words like NR. If one player was to say to another: "Hey my N*R, how are you holding up in your lane". If the context of which the word is used in is nonmalicious then it should under NO circumstance be treated as such. The impact of taboo words highly depends on the context of which it is used.
The riot language system should of course under no circumstance accept continuous malicious talk. Especially not when the game is played in addition to adults, also by children of whom are to be protected from harassment and verbal abuse. Even so, the language of which is spoken is based on the community of which is playing the game. Even if words like NR, FT etc. are regulated, absurdities will be taken to circumvent the restrictions. This is seen as people baiting the ban system by spelling the taboo words differently. NR becomes NUgger / Nagger / %%%%%% etc. FT becomes %%%get/Facts etc. If Children are playing this game, they always have the option to blur out foul language. A very good initiative from Riot Games. Yet, when the words become taboo or to some degree Illegal/dangerous to your account, people will find ways to use the language desired without the punishment of using such words. This is done regularly by misspelling bad words so that the automated system has no way of detecting it.
Additionally, riot has a way of banning the player from using words they allowed to be used in the first place. You are "Allowed" to say N*R, but are banned of such a word regardless of the context if you where to be reported that game, regardless of the circumstances. Either ban the word completely (Which I would argue is doing no good) or do not punish people for using the word.
Bottom line. The restriction of taboo words is of no actually good to the community. If they ought to ban words they should additionally not allow players to be banned on grounds of using a word alone with disregard of the context of the word. Thirdly, if they are to protect the minor community then disable chat completely for accounts with owners under a certain age. Or as a minimum restrict communication between the toddler-account and the well-behaving player base. If a player has a bad game / bad day / generally speaking is a douchebag, leave it up to the individual himself to decide what he will do. Players are handed the gift of the mute-button and are capable of disabling/enabling taboo words.
