AntiSignEdit
A simple Folia-compatible Minecraft 1.21.x plugin that locks signs after a player finishes writing on them, preventing any future edits.
Features
- Locks signs the moment the sign GUI closes after placement
- Automatically locks pre-existing signs (placed before the plugin was installed) on first interaction
- Works with all sign types: classic signs, wall signs, and all hanging sign variants
- Signs can still be broken normally
- Ops and players with
antisignedit.bypasscan still edit signs freely - Configurable message shown when a player is blocked (or disable the message entirely)
- Folia compatible via
RegionScheduler

edit-blocked: "<red>This sign has been locked and cannot be edited."
How It Works
New signs: When a player closes the sign editing GUI, SignChangeEvent fires. A region-scheduled task (Folia-safe) immediately waxes the sign block after the event resolves. Waxed signs cannot be opened for editing in vanilla Minecraft.
Pre-existing signs: When a player right-clicks any unwaxed sign, the plugin waxes it on the spot before cancelling the interaction. This means old signs are retroactively locked on first touch.
Bypass: If the interacting player is an op (player.isOp()) or has the antisignedit.bypass permission, the interaction is not cancelled and they may edit freely.
