Anti-Illegals

AntiIllegals is a Paper/Folia plugin that finds and removes illegal items before they wreck your economy, crash clients, or give players unfair advantages.

It uses named, fully configurable rules instead of a hard-coded blacklist. Each rule can target materials, stack sizes, enchant caps, display names/lore, CustomModelData, NBT signatures, potion payloads, written books, and nested shulker contents. Rules can run different actions — remove, warn, log, kick, clear inventory, or run a console command — and you can enable different rule sets per world.

What it catches

Creative/admin blocks (bedrock, barriers, command blocks, etc.)
Over-enchanted gear beyond vanilla limits
Scam/spam item names and lore
Abusive NBT / attribute modifiers
Illegal custom potion effects and oversized payloads
Malicious or oversized written books (including click/hover events)
Illegal items hidden inside shulker boxes (with nesting depth control)
When it scans

Player join, inventory click/drag, pickup, craft, container open
Periodic full inventory scans
Optional ground-item spawn checks and /antiillegal purgeground
Staff tools

/antiillegal reload|scan|inspect|list|toggle|purgeground

Built for Paper 1.21+ with Folia support.
