The Sims Wiki:Chat moderators

Chat moderators are users who are able to carry out administrative functions in Chat such as kicking and banning disruptive users. All administrators are implicitly chat moderators already. A full list of Chat moderators can be found here.

All chat moderators have a gold star next to their name to differentiate them from users who are not chat moderators.

What Chat moderators may do
Chat moderators are entrusted with tools to protect Chat from disruptive behavior by warning, kicking and/or banning disruptive individuals. Aside from this, Chat moderators are equal to other users of the Chat.

What Chat moderators may not do
Chat moderators may not use their tools to take advantage of users or to take over the Chat. They must not ignore the needs and wants of Chat users, and they must never use their tools for personal reasons or against non-disruptive users. Chat moderators which abuse their tools may have their status removed.
