AnvilBlocker

AnvilBlocker is a lightweight Paper/Folia plugin that prevents players from renaming items in an anvil to anything containing blocked words or phrases. When a player types a disallowed word into the anvil's rename field, the rename is cancelled and the player receives a customizable warning message.

Features

Custom blocklist — define any words or phrases to block via config.yml (case-insensitive matching)
Configurable deny message — supports MiniMessage formatting (colors, bold, etc.)
Live reload — update the blocklist without restarting the server using /anvilblocker reload
Folia support — built to run on Folia's regionized threading model, as well as standard Paper servers Lightweight — no external dependencies, minimal performance impact
