Be Warned, Auto-Clickers are at large!

So I've noticed that whenever i get into a non-ranked Twisted Treeline, or an ARAM, there are always some people who just walk out, and start attacking minions. They don't go for kills, they don't buy anything, and their abilities always go in the same direction. I think they have a program that automatically clicks for them that accepts the game, picks a champion, and makes them walk to lane, occasionally firing a skillshot in a random direction. I'm pretty positive that the only reason for doing this is to leave the game on all day, and to get infinite xp/ip. It is seriously pissing me off how people think they can ruin the game for everyone else, just because they are too lazy to earn their rewards. I think Howling Abyss, and Twisted Treeline should be disabled until there is a sure way to keep this from happening.
