Re: I have a question about moderators
They don't sit around all discussing every action before taking it - otherwise nothing would ever happen.
If a thread gets closed after being open for some time, it's usually because it has gotten out of hand or it's only just come to a moderator's attention. Sometimes a thread is being watched closely to see which direction it takes before any action is taken.
Every action is documented in the moderator forum though and is open to criticism from the other moderators. If someone disagrees, they say so and occasionally that leads to decisions being reversed after discussion.
Generally speaking though, most of the moderators appear to be of the same mind when it comes to moderating decisions from what I've seen.
