The TOU here, like most boards, prohibit posts that are abusive, harassing, etc, and permit the PTB (Powers That Be) to remove offending posts or terminate accounts.
In my experience, boards have a culture and are within that culture, self-moderating; in other words, posts that go beyond the norms are either reported or there is push-back from other members.
I played consigliere to one board some time ago (having nothing to do with audio). The amount of time devoted to dealing with zany users, snark fights and the like, was considerable.
This board seems to be fairly tolerant in allowing some in-fighting among posters, but will zap stuff that gets political or is otherwise inappropriate. I don’t think there’s much more that you can ask for; from my perspective, the moderation here is not heavy handed, and doesn’t seem biased.
I do wish the technological capabilities of the board were a little more advanced, but it serves its purpose.
