Ok so you don't seem to understand.
1, The knowledgable Admins conducted the investigation into this issue for you. No proof of further griefing was found therefore no punishment will be handed out (punishments would follow server protocol, not player suggestions). There is no evidence the player in question did destroy your base nor in a PVE server is this possible without leaving a trace.
2, Admins dealt with the initial issue of the TC, The floor spike were not dealt with as all that happened when the admin attended was you passed them floor spikes. There was again no proof of griefing in this and as you had the floor spikes in your possession no "owner" of placed entity could be defined by admins.
3, As far as can be seen no rules of Rustez have been broken as you suggest they have been so no editing of rules is required. I have no issues understanding the aspects of the complaint and the original complaint you made in server.
As said in my previous reply, If you wish to continue playing on the server, I recommend building at a different location on the map considering your existing issues with your neighbour.
Retaliation to an unproven accusation is not wise and may cause issue with your good standing within the community as per server protocols.
Thanks and have a Rusty day!
