Nothing but AFK in my games

My games have been nothing but AFK players ruining gameplay. Just played a game where our Riven went AFK, prompting me to do my best to carry. Was 9/0/2 at some point in the game and ended with 17/7/6, all my deaths caused by a fed Yi. This is getting so ridiculous I might just stop playing blind pick altogether. And no, so far for the past week, it was always my team that AFK'd or sat in spawn when the surrender vote failed.

Maybe Riot can put a frequent leaver on the other team and not mine?

This isn't even an issue with feeding, at least I can try and get some of my "bad" teammates fed. WTF do I do with an AFK?
