So...
In a recent game, I was told to kill myself twice by my teams ADC, draven, and I was verbally abused buy him, my team's support, and my teams jungler, all the while they refused to do anything akin to teamwork, letting me get camped by the enemy team all game without ganking or helping, and harassing me when I was killed because of those ganks, twice my jungler walking close to me and spamming laugh as I died.
Not to mention the insane amount of toxic shit they were saying in post game as I was reporting so I could leave, and they were trying to get the enemy team to report me saying I was the toxic one.
Guess what, shockingly it was a premade.
Guess what, shockingly no punishment.
