EzBlacklists is an official JonHosting plugin. This plugin adds its own /i and /v, allowing both commands to have their own blacklists. This plugin is primarily made for Creative Roleplays.
Within the plugin folder you can find items and vehicles files, both work the same way: permission,id,id2,id3...,permission2,id,id... and so on.

You can use AdvancedBlacklists, ExtraRestrictor (recommended) or ForceDrop to prevent players from picking up items instead.
