My understanding is that even on the Red server, if you create a claim then other users are unable to open your (iron) doors to gain access to your base. Therefore how is it possible for a user - who fell into my trap - to magically open an iron door within my claim whilst I was watching them? Looks like it has something to do with fishing / bobber if that helps?
it a thing in vanila minecraft that you can shoot a bobber through a door to activate a pressure plate. Use a lever on your door instead
Fishing rod bobbers can go through doors and activate pressure plates so the person u trapped was just smart or got lucky
