Why do I get so many inters in my matches?

i swear to god every 3rd match or so i get an inter in my game whether be on my team or the enemies. I'm not talking about the people so just play bad and go 2-16, im talking about the people who literally at lvl 1 and for the whole game just walk into the enemy team without even attacking them and die, what the f*ck, why am I getting so many of these people in my matches? report system does nothing as none of these people ever get banned, what on earth riot?
