A plugin that protects players' builds from griefers by preventing destruction and unauthorized access.
iqProtect
This plugin protects players' buildings and prevents griefers from destroying them! The plugin supports all versions starting from 1.13 and is easy to configure.
When a player starts building something, a zone is created around his building in which others are prohibited from breaking and building. The player does not need to do anything, everything is automatic! The zone itself will disappear when the player demolishes the building or the admin removes the zone himself.
