Well this is nothing new....but this year it will be worse. Cant tell you how many times in just the past week either someone on my team or the enemy team was either threatening to troll,int or afk in champ select because they didnt get their role and didnt care about the role they got. Or had someone on the enemy team asking for reports for someone on their team for one of the same reasons........... think ive had like 6 normal games where this didnt happen on either team. So this has always been happening, but with positional ranking it will be worse all season.
And does reporting them do anything? No because they just love to tell you how much they dont care because its their "smurf."
Their are a lot of people that wont like to hear this but Riot really needs to find a way to make people only have 1 account. If people wern't allowed to have multiple accounts they would think twice about being toxic.
