K/D Quit - When someone leaves a game before it ends just so they can l

When someone leaves a game before it ends just so they can look good on their stats.

I left the game after 1 kill and 0 deaths. My K/D is 1 to 0. I’m a champion.

I had 2 kills and 1 death. I left. Now it’s 2 to 0. I’m a king.

I left the game with 4 kills and 1 death. My K/D is 4 to 0. I’m a god.
