Well every1 were playing on pvp server with pvp jail i am sure, so i will tell ya one way when you cant die...When you go in jail start selling something for 1kkk so nobody to can buy it. Now you will be still mortal but when you die and click "To village" you will be at jail again and it automaticaly start selling again. Now no one can give ya trade ... if you are not selling anything and someone give ya trade it doesn't matter will you respond or not ... after that you will die if anyone hit you.
This is tested on a PvP server with a PvP jail. I hope it will work in your pvp server.
*ATTENTION*:This is only for servers with PvP jail.
