AFK problems

I bought a 3 day IP booster one day ago, hoping to play a lot of games (not even win them all or even half) and still have fun because im still getting my moneys worth. But today, i played 5 matches consisting in ranked, poro king, and normals on summoners rift. All of these games, I have had a teammate afk from the game either from raging because of his own performances, or others on our teams performances. I know for a matter of fact that everyone in the community hates playing with these kinds of people, but Riot Games does nothing about this problem. This really makes me upset though, because I just bought a 3 day IP booster and it really goes to waste when a game is unwinnable due to people like this. I realize that there are a lot of people reporting others in this game, and the scripting problem is getting worse, but not a lot of people get banned for these offences and really should. There is a leaver buster system for the people who rage quit, but Riot games should pay more attention to the people that afk at base but still moves so they dont get any penalty for not playing the game. I dont know what talking about it on here will do, but i hope someone reads it on here and it gets big.
