Riot, please tell me you are aware of bot accounts.

My last two games I came up with and against obvious bot accounts in ARAM. First game I forgot what champions they picked but it was on the enemy team, and I felt so sorry since they were just playing like bots and the other team could not do anything about it. Then just now, I played an ARAM game and I got matched with two bots (Xerath and Lee Sin) who just never used abilities, and jumped into 5 people on their team and made troll builds. Bots are ruining my favorite game mode in league and I really hope Riot is planning on a way to combot this problem. I hope that the people who made this account would be banned for life, maybe look at how they got referred to league and ban the person that did it. Is anyone else finding bots in their games?
