I know from the title of this article you may be a little weary of this but im gonna explain what this means and why it would be great

this rule would mean requiring players to make an entrance to their base and a way for raiders to access that entrance outside of a siege

why this would be a good idea

currently everyone lives in underground bunkers making it impossible to raid them if their claim is big enough (besides by in siding but that may takes months or even years) this is a massive problem for a pirate server as it makes one of the key features of being a pirate unavailable
deckhands and cadets rarely know how the server works so it makes them targets since their base isn’t underground so outlawing this would mean a more likelihood of deckhands staying
getting rid of the need to siege someone to get in a base could make it so you dont need the to find a new siege plugin
defenders would probably end up trapping their base making redstone more valuable
bases wouldn’t need to be griefed to get in making the map look better

the biggest problem i see with this suggestion is going to be the moderation of it as some players obviously wont follow this and may change their base as soon as they see moderation around them
another thing this wont really help is when raiding people you cant get most of their loot because its locked by chest

ps this would fit perfectly with no tpa as you wont be able to just spam raid someone because it gives them time to make preparations when you leave their base to stash loot
