There should be a way to protect you buildings in the wild I have a themepark in survival and it keeps getting griefed it would be awesome if there was away to protect it without making it part of a town!!!
Nope, we don't have protection sponges anymore. It's been tested and the best was Towny. Then again grief is not allowed so if you ever got griefed, come to a staff and we'll fix it. c:
