Strictly ban long time those who do not play seriously in PvP

I have to wait half an hour, then i just only heard a feed back from my teamate that is just for fun :| - but if they just play for fun why they chose starting in pvp where everybody need to play serious and earnest :\ - they can chose play with AI - where anyone can play for fun that is no matter - finally i think riot should consider my case then release some of strict optional to ban someone who act like this
