We (buu700 and I) added Gallowboob some years back largely to have insight into how other teams modded their subs at a time when we were growing quickly and needed to know what to do to keep up. While useful in meeting that goal, we quickly realized it was pretty meaningless for /r/relationship_advice because of the nature of the questions we were getting. The only sub like ours is /r/relationships, and we each differentiated from each other by having different rules and content creation controls.
As best as we know, Gallowboob enjoys the place and is pretty decent at modding, so we're pretty happy to have him. Most mods burn out quickly because of how dark the questions get as well as because of how meaninglessly violent people become when their posts are modded.

Separate comment on an item in the story:
> Allam believes his time on the site has made him a more “paranoid” person and led him to develop “borderline PTSD.”
Moderating Reddit's larger subreddits is absolutely capable of resulting in PTSD-like symptoms. I've been dealing with some on and off after a post some years ago where somebody who requested advice followed through with the best course of action only to find that his wife killed their kids soon after. And Reddit has absolutely no support system for things like this.
