Mods are volunteers, but most mods on SO take their responsibilities very seriously. The terminology that has been used during the last few days has been "firing" rather than "removal of moderation privileges," so I stuck with that.

Monica mentioned in her post that she was the second choice candidate for a community manager position, which is an actual job at SO, but I'm not clear on whether she was actually offered a job and if she accepted. Either way, this indicates she was a fairly active mod if she was being considered for a job.
