Complaining about AFK's

So i had an AFK Ekko in ranked recently he quit the game at the 2 minute so we cant remake my whole team were toxic and feeding. And as a toplaner i cant do anything about it. It ended up not being lost prevented and a game later i got demoted bcs of obviosly malphite support.. My main question is why do you allow peoples like this Ekko to even join games?
