Ok seems liek a good idea for a plugin but I couldnt find it (maybe I jsut missed it) so heres the setup player types in a command blocks they place will be un-editable to anyone but them they switch it off anyone can edit those blocks does it exist? am I just bad at looking?
I don't know of any plugins like this. I am no coder myself, but it would seem that in order to keep track of all these blocks you would need a mysql or sqlite database. That way it would put less of a strain on the server. It actually seems like a good idea. However I see it going bad too, someone turns it on and places unremovable blocks inside someones house. Of course there would be a admin permissions node that allows them to circumvent the check so they can edit players blocks if they used the plugin to grief. Honestly once you get into the whole MYSQL and SQLite its almost just worth it to get Big brother mod. It's not alot more work and it does a lot more without the certain downfalls you have with this plugin.
