As I understand it now you are not allowed to steal crops, but you can steal a whole building if you need the materials. But your not allowed to break other peoples creations. Its so contradicted its just plain confusing and impossible for us mods and admins to punish. The griefer only needs to say that they needed the materials and its all ok.
I vote that the griefing rules are like following:
Griefing is:
* You break blocks in someone elses creation, doesnt need to be claimed
* You claim over someones territory and then unclaim it to break stuff
* Destroy others creations
Allowed:
* Kill other players
* Steal from others chests, aslong as you dont break stuff to do it.
* Use tnt cannon to break a wall, not to destroy creations
Cause if we cant punish those that do wrong even thou the evidence are there, I will take it into my own hands and go Judge Dredd on every griefer I find and punish them in a way I see fitting. Its not abusing my powers, its my job as a Moderator to punish griefing with the tools I have. I am the law!
EDIT: As it is now ppl are leaving because they get griefed and the griefers gets away with it.
