PreventItemsUsage
Just a simple plugin to help preventing the usage of certain items in the world. Very good for creative servers or survival that want to block certain type of griefs or "bad jokes" between people.

Permission
Allows the usage of the blocked items.
- preventitems.usage

Config.yml
You can change the message showing whem someone tries to use the item/block and can add blocks to the list of items to deny the usage.
For default it only comes with "tnt" and "lava_bucket" which are the default most unwanted items if using a plugin like this.

Spoiler: config.yml

Code (YAML):

BlockUsed : '&cYou can not use this item.'

BlocksOrItems :
 - tnt
  - lava_bucket

Hope this plugin is helpful to anyone
