What AdvancedSensitiveWords is

AdvancedSensitiveWords is a free, open-source moderation plugin for Minecraft servers running Paper. Its DFA word matching and event-based inspection can check chat, commands, writable books, signs, anvil results, item names and lore, player names, and optionally broadcasts. Operators can configure matched content to be replaced or canceled, and set follow-up actions including commands, damage, effects, hostile behavior, or shadowbans. Version 2.x targets Paper 1.21.11 and requires Java 21; installation uses a release artifact or a locally built plugin placed in the server’s plugins directory. Optional LLM chat review is off by default and needs a compatible provider and API key. It reviews messages that pass the DFA and chat-context checks, with limits on message length, entropy, cooldowns, concurrency, and queue size. Requests and responses are recorded locally as sensitive operational data. The optional Velocity module supports notifications and proxy commands, but does not filter chat on its own. Other Paper plugins can use the shadowban API. The project is licensed under GNU AGPL-3.0.
