@Riot Something needs to be done about trolling in champ select

Over the past 3 days I've had 2 games where there have been players getting autofilled and choose to steal roles.

Game 1- Autofilled support player asks for mid and I say no because I just finished playing support last game where I was filled myself. This player goes on to lock in a mid champion and doesn't say a word. I did not want to dodge because it would have resulted in a 30 minute wait list so I go support. This player then proceeds to go 3/12 and claims "i dont really care if we lose". So not only does he take mid lane by force he then pretty much trolls the game by not taking it seriously.

Game 2- This happened today. We get into the game and the enemy team's Twisted fate is literally running it down mid. He says he is doing this because the Zed on their team was filled to support but chose to take mid from Twisted fate. Now inting isn't right either but stealing a role is pretty scummy.

My point is, it is season 7 and there is still nothing players can do about trolls in champion select. I shouldn't have to dodge every time someone wants to take champion select hostage. I don't know if there is a clear solution to this but something has to be done
