Technically, maybe. Special:ListGroupRights lists the rights assigned to each group.

The "moderator" group has these rights:
 * forumadmin (forumadmin)
 * notifyeveryone (notifyeveryone)
 * wallarchive (wallarchive)
 * walledit (walledit)
 * wallmessagemove (wallmessagemove)
 * wallremove (wallremove)

Too bad they don't have real descriptions. I imagine that "wallremove" is "remove" and "wallarchive" is close - but that's just a guess.

Ask Wikia Staff to give those rights to the "users" or "autoconfirmed" group.

If not, then yes, there's no reason why an admin couldn't just give everyone the moderator right if they wanted to do that - you should probably mention to Wikia Staff that that is your Plan B, it might help persuade them to just re-assign the rights to all users.
