Rules say that the title format is to be followed, but there are no indications of what it is, at least not here on the fediverse.
If this is a sister community of the subreddit with the same name, perhaps the rules were copied over from there but without adapting to how things are over here?
Reach out to the admins of the instance, they can check if the user is active and look for new mods. If you want to moderate it then even better :)
Same with @[email protected] and @[email protected]
