Some concrete examples...
At Sharkmob, that person is called a "Player Relations Manager", but his role also includes the player support-department, and we're all part of marketing, which is a separate thing from PR (Public Relations) or the Studio Communications department for that matter.
Then you have some studios who have "Social Media Managers", who essentially are the specialists who manage the social media, but some of them are strategists, and (again) some of them manage a group of "Social Media Specialists" who manage the social media.
Any of the above might do it, and some of them rely on Copywriters to formulate articles, copy for social media, or just go through documents intended for internal use (by moderation staff).
Baking responsibilities in roles
Speaking of moderation, some or all of the above might be directly or indirectly involved with moderation of Reddits, Discords, or Steam Forums, or any forms at all for that matter.
This industry seems to be quite reluctant to stick to clear roles (in terms of both name...) and expectations of them, so when I sometimes spend time looking at what responsibilities some of my colleagues have, I nod in recognition. But at other times I'm baffled by some things that my fellow community people do.
For example, I saw one "Community Manager" who listed: "Creating Ad campaigns for physical, AND digital media" as well as "Creation of Video Assets for said physical, AND digital media".
Big studio, fewer hats? Small studio, more hats?
Now, of course, I realize that in studios where there might be a small number of people, one might have to wear many hats. But this guy is working at a rather large studio, responsible for more than one AAA-game.
I'm also sometimes baffled over how some "Community Specialists" have a responsibility to "Manage a community JIRA" ... "plan, and delegate tasks" to other "Community Specialists". That almost sounds like a role that I've never seen anywhere (yet)... are there Community Producers, or Community Project Managers out there? (I'm genuinely curious).
There's no standard because we're nerds?
I sometimes wonder why this isn't standardized, but then I remember that the gaming industry comes from a generation of people who saw (and were seen) as people who worked with games for pure passion alone. With that comes the confusing situation of going from "alone creations of cool games for fun" to "the mess that is creating cool games for fun together" and the organization of said mess. Including coming up with names for things.
Back in the day when I was a part of "The Scene", I had roles ranging from "Cool Dude" (or Hangaround as the much cooler Motorcycle Clubs used to call them) "ASCII-artist", "SysOp", "CoSysop", "Graphics Artist", et cetera.
There wasn't really a point of reference for these, because computers kind of "popped up out of nowhere", and while "artists" have existed for ages - the digital form of artistry certainly was new, and as all new things: a certain stigma was involved.
I think that's one of the reasons why some of us, when working to legitimize what we did in society, we borrowed some words from "the established industry". But because this effort was done completely without any communication amongst one another, the names of these roles kind of became similar to how we used to compete at LAN-parties (back in the 1990's they were something completely different: much less about playing games, much more about creating digital things together).
But because most of us were boys, it wasn't all that unlikely that there would be competitions among one another. As someone who was considered "lame", or a "lamer" at one point, the struggle was real. I had to prove that I had a skillset worthy of recognition. Somehow.
