Is there a plugin to destroy certain items through a map? like i have banned an item from being crafted but some users that have placed the item can still use it? its a tekkit item also..
Check out this plugin: http://dev.bukkit.org/server-mods/tekkitcustomizer/ It has an option to block items and it deletes that certain item if he founds it in the map or in a player's inventory. It's mostly used for Tekkit but it might work for you as well.
