I recently built a Keep in Felucca on Pacific. It is in the Yew VvV zone. If I make the Keep open to the public can other players come in an attack me and my guests? Or is housing considered a safe, violence free, place?
If it's open to the public, you are vulnerable. One solution may be to allow some areas to be public, but 'lock' some doors via the context menu to keep you safe, setting them to 'friends' or 'co owner' access. Some openings could be closed by using tinker crafted doors.
Lock ur front doors (set for only ur use) then get some house tele tiles. Put 1 on the outside steps & the other inside, set them for friends only.
