Downvote Brigading of Moderators who Say Hard Truths

I have noticed that when a moderator says hard truths to a toxic player who started a thread, all the moderator’s posts can wind up down-voted to -6 or -7, especially if they go back and forth. I think that these players are organizing or benefitting from mass-downvoting of the moderator’s posts. Can the moderation team look into this, please, and hold accountable those responsible if brigading is indeed discovered?

Edit: Oh dear. It seems I’m at -1 already. Maybe they’ve come for me!
