Where is a better way of getting trolls reported and banned...

Just had a game with a premade who got bot and support. The first thing they said was "IM GOING TOP" and "IM GOING JUNGLE" and proceeded to play in those lanes without anyone saying so, int feeding, trolling, etc. Obviously the enemy team condoned this and called us shit like "pussies" for complaining about it. This community really is just utter cancer to condone the bullshit these kids do. I would gladly give out the IGN of these plebs if it'd help but the dumb ass league rules wont allow "naming and shaming" which is %%%%%%ed.
