Player joined the lobby, called out a player in the lobby as a hacker and left
No-one had locked in yet, the match still started
Turns out, he was (aimbotting and/or walling). My guess is this first player had already played a match against him, based on the, plain distasteful and egregious bad-talking the Hacker was doing.
If someone dodges out of a lobby like that, they’re not coming back, I thought the MM was supposed to cancel out and not start the match.
I neither blame the guy for what he did, nor do I think he shouldn’t get a, minor, MM penalty, just the match started out uneven.
EDIT: Just noticed the autocensor
