Actually, some of the mods have resolved some of the issues; they just don't post in the Staff Notification Board (I know this because some of the offenders have been banned).
I've simply put into place a new rule to clamp down on this a bit - gravedigging results in a 3-day ban (with an extra day added on for every reoffence).
I have banned the following members:
* eiridas001 - 3 days
* drachir15 - 4 days
* nero trunks - 3 days
