To be honest, I probably can’t give you a link to it because - luckily - we’ve never had a case where I’ve had to verbally moderate. Or do you remember @Negreheb ?
My work so far has been limited to splitting posts in the Austrian forum.
I have made myself available as a temporary moderator during the voting phase in the German forum. Things actually escalated a bit among the discussants there, but I probably had to search for a long time for a relevant post in the entire discussion thread.
I remember at least that there were some user bans back then.
