From what I understand about how the queuing system works, it is not the fault of one player requeuing and dropping hundreds of times, troll or otherwise, causing this but the result of 72 players queuing at once.

Consider how often you have either failed to confirm or withdrawn because of something, and realize that 71 other players are in your exact same position.

If there is a 5%* chance for someone to withdraw or timeout and 72 different "rolls" then there is a near 100% chance that someone will withdraw or timeout.

*example, not an actual statistic.
