Can anything be done about smurfing?

I'm seeing so many smurfs come into these matches and straight stomp the game. ITS NO FUN OR FAIR TO THE REST OF US. How do I know they're smurfs? Well I'm in plat and when I get a "silver" player with a 70 plus win percentage who stomps the match, yeah that's pretty fucking smurf like to me. Like seriously, it's ruining what shred of fun I have left in the game. Will anything ever be done about it or does Riot not give a shit like with everything else?
