If you rage at someone ingame or purposely feed/afk then youre a bad troll
Every troll with 1/4.234324324 of brain knows the best way to troll is by playing support, jungle, or adc. Instalock support and place less than 10 wards within 40min, congrats you've just ruined someone's game and wont be banned for it. Instalock jungle and dont gank within the first 16 min and 30 stacks of devourer, congrats you've just ruined someone's game and wont be banned for it. Instalock adc and miss a shit ton of cs so you will fall behind in gold and wont be able to carry late game, congrats you've just ruined someone's game and wont be banned for it.
Rinse repeat, and voila you can continuously ruin games and not be held accountable.
