i would love your opinions on this

we all actually rage in game and sometimes we are toxic and so, but ive actually just played with someone who literally said "i'll kill you and your family, BOOM you are dead and he went on and on" i did report but idk if anyone is going to take an action and i think this unacceptable, i think people who talk like this should be perma banned, without even a notice on it, because we all here are playing for fun, so why do people threaten to kill others in a game? riot please do something about this.
