Rage quiting penalty

Riot i want to ask if u can make something like a bigger penalty for rage quitting cuz i just had 3 rage quitters who fed and flamed we reported them but 3 games in a row is a bit too much :D ? I know all of us have experienced rage quitting some have even done it and no one likes it except the enemy team (lets be fair here :D) before when i was playing another game there was an ingame voting 1 week ban system all 9 players voted and if they had 9 outta 9 the player votes for yes the leaver was banned for 1 week can u feature something like this in the future ?
