One fairly busy forum I cofounded and "moderated" on, we intentionally call the moderators "Janitors" in an attempt to dissuade the sort of people who wanted "a powerful role" from even wanting to ask. It sorta mostly worked, largely because there were 7 very like minded cofounders of that forum who stared it as an escape route when a previous version was sold to a forum-monetising company (Vertical Scope, from memory).

“Moderator” used to sound like a boring role as well once upon a time.
