I won't say which fandom it is for but I just became a content moderator of the wiki of a new Japanese multimedia project! The project is big in terms of popularity, but currently only 10% of what it has to offer is revealed, so its current content database is small. So far on the wiki it's just me and one other person, so, my guess is the most I'll have to do right now is add content when the other person is away, rollback vandalism, delete unwanted pages, and get rid of inappropriate comments.

I'm the bureaucrat and founder of a wiki based on myself and a wiki for an archive (it's not really an archive anymore), and the former bureaucrat of a fanon wiki, the latter of which I got on a platter. I also did some major edits on a movie wiki aiming for administratorship, but I never got the courage to ask the bureaucrat of that wiki (who is active on other wikis but not said movie wiki) upfront.

That means being a content moderator on this wiki is my first foray into seriously moderating a wiki! So I'd like to list my duties as one according to Wikia itself:

"Content Moderators are users who have additional tools available to moderate specific parts of the community. These tools are:

•    Editing and moving fully protected pages
•    Deleting and undeleting pages and files
•    Editing and moving protected files
•    Rollback
•    Protecting and unprotecting pages
•    Patrolling pages if the community has the recent changes patrol feature enabled
•    Deleting and undeleting article and blog comments
•    Deleting, undeleting, editing, locking, and unlocking message wall threads"

So when people are vandalizing pages, I have the ability to quickly rollback changes. And if people are being harmful, discriminatory, etc., I have the ability to take action against them.

Something else that comes with it, evidenced by why I got the position in the first place, is that I add new content to the wiki. For example, if an album is announced, I am one of the people on the front lines to make a page for it.
