Never Play With Players You Report

So i just played a game in ranked and i got to say it is very stressful to play these games when there are people who throw games intentionally and ruin the fun of League Of Legends... now i try my best to be calm, collected, and helpful. That being said i do tilt because of these troll players, i love this game and wish i could play it without any toxic players, i do understand that is really impossible to accomplish so i have come up with this idea and i am looking for thoughts to see if anyone is also thinking the same as me. Would it be possible to have a system where if we report a player for what ever reason we see fit, we will never play with them again or at least for a long long time. i have played 2 games in a row where i was stuck with a troll after he threw the first game only to throw the second. it sounds silly i know but i didn't see the name until the game has started and i just reported him, regardless i feel like there should at least be a player separation if they report each other.
