So i just played vs an entire team of botters in ARAM

Stand around doing nothing, they all clump together in the same spot, when you go in the bush they forget you ever existed when you exit it they cast all their spells perfectly with 0 reaction time. In both games a Sion build AP and when in passive runs back to base without ever hitting anyone. Does Riot cares about player experience? Why not make a maximum IP gain per day to discourage botting if you do not otherwise posess anti-botting measures?
