Auto Fill Means Troll?

The only reason I am writing this is because I have a very long que because of this problem. This seems to happen a lot for me and my friends I talk to and something needs to be done about it. I get on today and my first 2 ques both have an auto filled person on my team. They ask to swap and no one does (because people like to rank up their main positions now). Both times end up in the person just locking in a troll pick and saying how it doesn't matter if he trolls because it won't affect his main lane rank and only their support ranks (both time the support got auto filled). This is getting pretty stupid because the players who actually want to play have to suffer by either dodging and getting a long que timer or by wasting 15-25 minutes with someone who has no intention to win the game and getting a free loss on our main ranks. Do you guys get this problem at all?
