Can we do something about the massive ammount of smurfs outside ranked already?

Game is unplayable thanks to 99% of accs being diamonds in non ranked games. Can we get forced phone verification already? I'm sure no sport allows middle league players to disguise as simple casual players with about 20 different identities and join friendly games for the sake of not letting nonpro players play, yet in LoL this kind of selfish behaviour is not only acceptable but REWARDED.
