This plugin takes commands such as /plugins, /bukkit:a, /?, and so many more and blocks the plugin list and redirects it to a custom error message to your liking!

Features

• Block players without permission to view plugins
• Custom error message
• Bypass permission

This is much simpler than other "plugin hiding" plugins and easier to understand and really just get straight to the point. Adding just some more lines of skript code you can give the player debuffs, messages, and other features to your liking!
