Horrible report system.
My biggest problem with this game isn't that people get banned for being toxic. If that's what RIOT wants they have every right as a company to set rules that people should follow in games, and should be able to dissallow certain language from their games as well. My biggest problem with League though is that they instantly ban people for being toxic, but then people who troll or are just shitty teammates in ways besides being toxic seem to never get banned or restricted or anything. The report system is basically if you're not toxic you don't get punished which is honestly bullshit, and completely backwards, id rather have all the toxic players that continue to play the game over the people who run it down mid or afk farm after the smallest thing.
