Greyson has a zero tolerance rule in regards to griefing. There are quite a few signs when you are leaving the spawn that states you will be banned for griefing.
On Bastion the rules clearly state do not grief, and we do not have to give you any warnings whatsoever.
First of all, I do not know what blocks I have griefed that I did not replace. I destroyed blocks to get into chest, however I replaced them. Any other blocks I have griefed, I am unaware of.
Also, If you believe a sign saying, "Do NOT Grief", suffices for an actual person who can enforce something telling you to stop and replace all the blocks, that is your opinion. In the rules it states,
Abandoned structures of inactive players can be claimed. You can check for inactivity by looking a sign containing the owner's name and using the lastlogin command (/lastlogin <playername>). Inactivity is generally defined as not logging in for a period of one month or more. If the player is inactive or there is no sign on the structure, the following procedure applies.
- Place a sign in a visible location with your name, date you placed the sign, and intent to claim. (Do not remove this sign, as it is used to confirm the claim date by admins/mods)
- Wait one week from the date on your sign.
- Submit a petition (/pe new <message>) with your request to confirm the claim. Be sure to include coordinates of the building. A Staff member will check your claim. They have the final say in all claiming requests, and have the authority to deny you.
The purpose of the petition is to ensure the structure is truly abandoned. Many times players will have notified staff they will be on an extended vacation or military leave, and wish their structure to be protected.
However all of the blocks, houses and chest I may have destroyed were not claimed with any signs containing the owners name, date of claim, and intent to claim, actually, I have never came across a house with this. Unless you are just not allowed to destroy anything man made, unclaimed or not, then I would not know why this has happened.
