HAS ANYONE ELSE NOTICED THIS?!

So, you're playing 3v3 and you notice one of your teammates auto-locks a champ without saying a word. You don't make a big deal about it and you pick your champ and your lane. The game starts and you notice the auto-locking noob on your team just strolls into bot lane and just stands there auto-attacking any minions close by. When the other team annihilates the noob, the process just starts ALL OVER AGAIN. He respawns, walks into lane, auto-attacks, then gets killed. You try reasoning with him, yelling at him, threatening to report him, but NOTHING WORKS! He doesn't say a single thing ALL GAME.

I've experienced this three times in the past two days. My theory is that people are using an auto clicking program just to get into games for easy IP. That way they won't have to sit around the computer to get IP for the newest champ. They can just go AFK. This happen to anyone else??
