Bots are rampant

Four bots all together in one aram game. Three bots on my team and one on the enemies team. Its crazy to see the amount of games each bot has as well. Someone takes the time to play the intro games out and then just lets the bot loose in aram. How can riot just let bad practices like botting just go on without any sort of repercussions.

There is either quite a bit of money to be made in level 30 accounts or riot is just padding lower level games with bots for the sake of que times.
