Ya can't, ya simply can't get rid of them.
I agree with @ArianaGrandeVevo . It's really not that big of a deal. Teamers will eventually show up no matter where you go and crying about each time you see one like this isn't going to do you any good. The punishment is more than cruel for teamers so I don't know what more you want to feel secure when playing a 5 minute game.
