there are moderation abilities, but instead of all-seeing global moderators it must be done by the little poor room owner, and the mods they have granted permission.

if the existing owner/mods don't do that, and disgusting content starts appearing in the room, that means they probably aren't active anymore, and that it's time to make a new room with the still active members before something even more damaging happens, like an uncontrollable high volume spammer, at which point you won't be able to tell the others that you have made a new room.
