STOP LETTING AUTO PICKS

so, I have come across over the last 2 months at least 16 games where some **** head joins and says the lane I am in AFTER me. I have too play the whole game while they feed and we die cause of it. they have mostly been yi's and because I main lee jg, they say " jg or feed" and that crap. IIM SICK OF IT, THEY SHOULD BE HUNTED DOWN AND HAVE THEY'RE ACCOUNTS LOCKED, plz do it cause I can not go through it any more, I get annoyed enough at l.o.l. and I don't need some loner ***** to make it worse.
