This guy has over 12,000 betrayals in less than 6,000 games. These are not accidental kills, he intentionally betrays his teammates.
This number of betrayals does not reflect his actual amount which is much higher, but since he will wait until you are shot by the other team it gives his betrayal to them.
He is a scourge on the community and I have brought him up here before, and yet nothing is done.
The MCC playlist is a wasteland of betrayers, team shooters who are too smart to betray, afkers, controllers given to toddlers, and literal willow branches.
If we had any moderation whatsoever, at all, this would have been fixed ages ago.
