1. Place a laptop/camera or something into a stash and bury it, record log of players that enter and leave radius

    Example, Juke Alert, Minecraft mod:

    Home · Civcraft/JukeAlert Wiki · GitHub

    This gives players ability to know who entered/left their base,
    could potentially let you know who looted your boxes or griefed your base

    Theres another plugin called Box Looters: BoxLooters | Oxide
    But it is an admin-only tool at the moment (and once players know about this ability they could just destroy the boxes after they steal from them)
     
  2. This is a cool idea! i will do up a prototype this afternoon when i get home
