There seems to be a bit of a misunderstanding about what is going to be allowed and what is not going to be allowed. The two lines in red do seem to contradict each other in the context of what I am about to post.
It is expected that you will play fairly within the spirit of the server:
-You will not excessively grief someone's land: grief to break through defences and to fight, not to simply wreck their stuff.
-You will not go overboard with Obsidian in order to make impenetrable rooms or forts.
-You will have to claim land before declaring war on another faction.
-You will not claim lands purely to allow you to attack other people while leaving your own property undeveloped.
The server is semi-griefing enabled: Land is protected when at peace, only when at war will enemies be able to grief. Please note that any buildings on un-owned land are not protected under these griefing rules. If you do not own the land, it is fair game. Build on Wilderness land at your own risk.
Last night someone destroyed every block in the corner of a building that was mostly protected. Every block was technically in the Wilderness through an oversight in the land claiming process. The faction claimed an area of 68 chunks and happened to miss one.
While technically within the rules, this is a violation of the spirit of the server. Its obvious from looking at the layout of the land, and the money this faction has in the bank, that they did intend to claim this chunk. They own every chunk surrounding it, and have plenty of money so that they could have claimed this one too. And this is at their main faction claim. This is information available to every player in the game.
If this had been an outpost, or someone taking advantage of a hole in the defenses to go in and look for stuff, or someone who intentionally built a big fort out in the wilderness then I would not say a word. But lets not destroy someone's entire creation because they made a mistake when claiming the land. That is just wrong.
I got asked about animals this morning too, so I will post on that as well.
If you manage to find a way into someones base and their livestock area, its ok to kill a few cows or sheep or whatever. After all you have to eat!
But if your intent is just to kill everything they own then at least have the balls to declare war and to do it while they are online and can defend their stock. Animals are not protected by plugins and this is something we will have to make judgement calls on, and I would say that killing all of someones cows was just pure griefing.
Wolves are a different story since they are also weapons. Steal them if you can.
