Why do people automatically match games when they're not at the computer

Teammates stupid let me lose a game, I quit, match has been disabled, so I went to the toilet, and then drank a bottle of drink, back to the computer to see, a new game started, three teammates quit, the enemy is burning my TC, lost again, this is the third time I am not in front of the computer but automatically start the game, I left the computer because the match has been disabled, Why does it start automatically?? It usually takes five fucking minutes to search for a match, and I’m not at the computer and I get a match on the spot? FU! relic!
