Punish AFK!

Seriously, I am totally fed up with all these AFK players. I play ~3 games a day, and in one of them there is always an AFK on one side. Today, ALL three games were decided by an AFK player (2 wins 1 defeat for me).

Since many people brought this topic up and still punishments are not raised to a serious level, I will now repost a similar thread every day I got an AFK as a reminder to act. People may follow my example if they want. I know this is not the most beautiful way to raise awareness to this, but I am really, really desperate. I just don't know what else to do to convince Riot to change things. Tell me, please.
