ADC was trolling we all reported her to no avail.

Hello people... I woke up this morning feeling happy, thinking that a i got a litteral troll on my team, the other day banned. She was flashing in fountain and was healing on the way to lane. (Plat 5 MMR) We got invaded and our support dies... IT HAPPENS!!!. But she went absolutely crazy and started feeding after telling Nami to leave her lane so that she could solo the lane. Nami wouldnt hear of it and stayed botlane and she then decided to start feeding the enemy team. The enemy team agreed that it was obvious trolling and reported her aswell atleast 3 enemies and 4 teammates reported her. But im SO confused... i can still see that he's playing games and doing a horrible job at it. Is this what they might mean with "Ranked" maybe being "Rigged"????

Riot, i would most of all want a answer from you, as it's your game and it's you guys who know's how this system works. So far you've just let a player ruin other peoples games. Hurraaay........ [slayer-jinx-unamused]
