Fair, it’s just certain bullet points seem to define actual metrics which strongly suggest automation, particularly:
Abusive chat reports will fall off after a predetermined amount of time.
The number of abusive chat reports necessary to penalize your account remains the same, regardless of past penalties.
The first bullet indicates there’s a rolling period for counting reports, and the second bullet point indicates there’s an actual threshold that will trigger the silence once the threshold is reached.
I can’t imagine GMs being bound to thresholds if it was a manual review.
