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.
