ARAM bots

Since I saterted a new account I noticed that there are lots of bots in ARAM, like 20% of the 'players'. They always build the same, always spam random abilities and always ruin the game for the other players. They are easy to spot since they always do and build the exact same thing. Why does rito do nothing against this bot spamming?
