What you guys need to be careful of is losing sight of your role to "Greet" and turning into some kind of self-appointed vigilante force. If you're seeing an activity on MOULa that you think is questionable and can support it with (some) evidence then report it to http://support.cyanworlds.com or by PM/email to Tor'i (or to Dog if you happen to see him in cavern, but PM/email is usually better). I've been successful in getting accounts closed down before when the owner had created offensive avatar names. Cyan can't stop someone coming back with a new email address but they can block a user by IP address if necessary and they also have other techniques that they're a little less willing to talk about.
However, there's nothing in the TOS that says that someone can't flip avatars, create and delete them at a whim or anything of that sort, so if there's a complaint there it needs to be based on actual griefing that can be documented to be affecting other players, and not a suspicion that something is happening.
Just throwing in my tuppence worth as a MOUL mod
