1. As admin i can use glowing eyes as cosmetic or for example can give myself bleach in test server. But that stuff can be looted form my body if die form other players. Can restrict filtered items form being looted or despawn when someone try to loot them. Please reffer plugin which can do it it its possible.
    Thanks in advance.
     
  2. ComponentBlocker possibly?
     
  3. Lootprotection to keep your body from being looted at all?
