Better Item Ban

This mod adds 4 commands which lets you ban specific items. 
Items that are banned get instantly removed from every players inventory and are no longer obtainable.

/itemban add <item> — bans an item (tab-complete works)
/itemban remove <item> — unbans an item
/itemban list — shows all banned items
/itemban check — clears banned items from all online players right now

you need op level 2 to use any of these.

example: /itemban add minecraft:tnt
