What is LeaverBuster?
LeaverBuster is a system we have implemented in order to discourage Summoners from repeatedly leaving matches and/or idling during gameplay. Summoners who exhibit this behavior and have a trend of leaving/idling in games will be placed in a low priority queue.
I just disconnected from two games! Am I going to get banned?
No, your account will not be banned. However, it is possible to be punished for leaving just 1-2 games. Players who leave games will be placed in a low priority queue and will be required to play 5 matchmade games without leaving before exiting low priority queue.
Note: Leaving ranked games is considered more severe than leaving normal games.
Are ranked, normal, and co-op games treated differently?
Ranked is treated much more severely than normal when it comes to leavers. Games in which a player is considered a leaver always count as losses for them, even if their team is victorious.
I left a custom/tutorial game and I got a warning that my account may be punished? I thought custom games didn't count?
They don't. This message will appear every time you leave a game, but custom and tutorial games will not increase your risk of low priority queue. LeaverBuster only applies to games you have to queue up for, such as normal games, Ranked, Co-Op Vs AI, etc.
My game keeps crashing/disconnecting. What can I do?

About Low Priority Queue
What happens when I leave a game for the first time?
After the game, you will see a pop-up with a LeaverBuster warning. You must follow the prompt on screen in order to queue and play additional games. This does not mean that you've been punished, this is merely a warning. After leaving several games, you'll receive a notification that you've entered the low priority queue.
How long will I remain in the low priority queue?
You will be placed in the low priority queue for 5 games. If you continuously leave, the low priority queue timers increase from 5 minutes per game to 20 minutes per game.
What happens when I leave/dodge a game after waiting in the low priority queue?
If you dodge during champion select after waiting in low priority queue, you will have to go through low priority queue all over again even if you already waited through it before.
What happens when someone else leaves/dodges a game after I waited in low priority queue?
If another player dodges during champion select after you waited in long priority queue, you will not have to wait through the low priority queue again. You will instead just wait in the regular queue for another game match to be found.
What happens when I cancel the queue that I was waiting in?
If you cancel either during the low priority queue or the regular queue afterwards, you will have go through the low priority queue again from the start.
Can you take me out of low priority queue?
No. We will not take your account out of low priority queue under any circumstances.
I crashed and got a leave/MMR loss. Can I get those removed from my account?
Our system does not allow the removal of leaves or the modification of MMR. It was designed in this manner in order to prevent corruption.
I'm a paying user. Shouldn't I get a bit of leniency on this?
No. Every Summoner contributes to their team's victory or defeat on the Fields of Justice. Those who repeatedly leave games or idle during gameplay hurt their team and the overall experience of all Summoners on the field. In order to discourage this behavior, we must take action against those who make it a habit.
It's not my fault. My internet/your servers disconnected me. I had a real-life emergency. I had to get off the computer. The game crashed. Unban me!
We understand that players may be forced to leave from time to time so the system has been designed to keep these situations in mind. After leaving a few games, you will be placed into a low priority queue; as long as you can complete 5 matchmade games without leaving, you will be returned to the normal queue. However, if you continue to leave games, you will remain in the low priority queue.
