DupeProtect // Fixes duplication glitches and server exploits (Dupe Fixes)

Automatic Updates
This plugin will automatically update when a new version is available!
Added in version 1.14.8!

Punishments
This plugin has a punishment system that will ban you based on failed attempts to interact with a duping method without permission. Some of these interactions have been disabled in creative as it could cause players to be able to ban themselves easily. This feature can be disabled in config by changing punishments to false.

AntiBook
Use this feature to prevent chunk duping with written books.
This feature disallows all users from interacting with book and quills negatively. Patching this dupe glitch.

Administrators can still use books with bypass permissions
and players are able to read books unless they contain illegal characters!

Prevent Duping via the book and quill.
This plugin will make it so all users without certain permissions
cannot access the item book and quill, this includes but is not limited to crafting the item, using the item, interacting with the item, or having the item in the user's inventory. All players are still welcome to interact with books however, but only people with certain permissions can write them.

Users will be punished if they are repeatedly caught interacting with the book and quill item in a negative way.

You can toggle this feature on or off in the config.yml file or in-game by typing /antibook as an administrator.

You can bypass the plugin with the permission dupeprotect.antibook.bypass or with operator on the server.

AntiPV
Patches PlayerVaults and PlayerVaultsX exploits
Cannot open pv whilst standing on a Lily Pad or Carpet Block!
Lots of customization.



You will be kicked if you attempt to type the command too many times, administrators will be warned when this happens.

Feature will not be active without the PlayerVaults or PlayerVaultsX plugin enabled on your server!
Config File
Enable or disable this feature in the config.
All messages have customization through the config.
Use <player> to target the player and <block> to target the block!

EX: disallow_message_antipv: '&eYou cannot use this command on the block <block>!'
Other Exploits
Make sure to report exploits that include duping or another issue and I may fix them and implement them into the plugin!
Config File
You can set the configuration of the messages sent to the users and admins here, and you may also disable those messages if you chose to do so. You can also disable the plugin entirely here. The chat messages are fully configurable and use chat color formatting with the character '&'. You may also use the text <player> in the admin message to specify which player has interacted with the item.

EX: disallow_message: '&4This is the message displayed to the user who interacts with a book and quill.'
