Support. I am so mad because I have a cobble monster right outside my sky island platform thing, and I gave up long ago trying to remove it. It's very annoying!
Support. Reasons: 1. Griefing is considered trolling/harresment. 2. Survival has another name which is: Anti-Grief Factions, but what happens is that griefers made Survival exactly Factions but you cant overclaim on Survival while u can on Factions.
This would be pretty useless to make against the rules unless mods got access to coreprotect (ability to see who griefed). It's the player's responsibility to claim what they don't want built on. Players can also define "grief" differently than others. Some may consider placing a cobblestone block outside of their land grief? If this were made a rule, where would the line be between grief and what's not grief? Not that I don't find it extremely annoying and awful when players do this, I just can't see a way this rule would work properly.
Alright. Seems like I already covered all the topics you mentioned in the thread itself. But alright.
The only thing I addressed as a concern that you already mentioned was this: Despite your explanation, I was still iffy on this part.
