ChatSentinel vs PunishBAN

ChatSentinel is a self-hosted moderation plugin for Minecraft Paper servers. Its local trie filter checks chat and can load word lists for 28 languages, with leet-speak normalization and abbreviation expansion. It can also moderate whispers, signs, books, and anvil renames. Flagged content can be blocked or masked, with configurable escalation to warnings, mutes, or staff alerts. Optional moderation API and LLM review layers can add checks; both are disabled by default, so the local filter can operate without API keys. The first layer uses an OpenAI-compatible moderation endpoint. The second accepts compatible chat-completions providers, including Ollama, LM Studio, vLLM, Azure OpenAI, Together, and Groq. SQLite is the default database, with MySQL and PostgreSQL also supported. An optional PlaceholderAPI integration exposes moderation-related player details as placeholders. The README lists Java 21 or later and a Paper server as requirements. It describes a fail-open pipeline: local filtering remains active if APIs are unreachable, with a configurable timeout before messages pass through. ChatSentinel is free and open source.

PunishBAN is a lightweight punishment plugin for self-hosted Paper Minecraft servers. It handles bans and mutes for players who are online or offline, using presets or custom durations and reasons. Its chat filter checks configured terms without regard to capitalization and normalizes leetspeak. Staff can receive clickable ban and mute alerts, with a cooldown to limit repeated notifications. Three filter violations within 24 hours trigger an automatic 24-hour ban; a violation in the racism category results in a permanent ban on the first offense. The `/playerinfo` command shows a player's UUID, first and last login, punishment status and alternate accounts that share an IP. `/banlogs` displays ban and mute history, listing the last 10 entries. Presets, filter terms and durations can be configured in `config.yml`. The plugin stores data in YAML files and does not require a database. It supports English and German, which can be switched without restarting. Its requirements are Paper 1.21.1+ and Java 21+; LuckPerms is recommended for permission management.
