Stop putting me in already in progress games!!!

I am sick and tired of joining games that are down 1-2 or 0-2, and only being able to play 1-2 rounds until I loose! Just now, I got put into a game that was on overtime match point, meaning that I didn't even play! WTF?! I understand that the people that i'm joining are at a disadvantage without a 5th player, but why the hell does that 5th player always have to be me? Every single game i've played today, I got put into a match that has already started. There needs to be some sort of limit to how many times this happens. Just because you are queuing solo, does not mean that you are a board of wood, ready to help fix up the leak that is a 4v5.
