There is a planned "Anti-Griefing" update, there is a -> wiki page for it.I have some remarks and questions regarding it that I don't see covered in the wiki.Who can work on a distinct building depends on which building it is, not who are ones friends or (temporary) group members. People participate in building and maintaining several and sometimes many structures, so having an agreement to participate at one site does not automatically mean having an agreement to participate at all sites. How is that addressed in this update?When a group member places some blocks and later leaves the group (or changes friendship status), how will the remaining members be able to break that blocks and change the structure?When a group builds a structure, will the blocks "belong" to each member that placed them, so the ownership is a mess and changing becomes a nightmare?Griefing by stealing blocks is bad, but IMO, griefing by placing blocks is even more frustrating. IIUC, anyone can come, turn buildmode on and place dirt all over a structure, or perhaps even worse: in carefully chosen places - and others won't be able to remove it. How is that addressed?How about public structures?Example: someone repairs a public road with a full block because they don't have a slab at the time. How will others be able to remove it and place a slab?Will it be possible to turn off the protection - to place (non-common) blocks that are not protected?People could (will!) start using protected block walls to protect land / structures / farms / grinders. How will that be addressed? A: They can if they like, provided they build around their own structures. Simple walls wouldn't be dependable protection because they can be glitched through.With proper land claiming and appropriate permission system planned, does this Anti-griefing update make sense?Would it be better to have just a simplest land protection ("Land Claiming 0.1") until the full version is implemented and tested?Answers are WIP.
