Moderation Log
Moderation Log Tool is a Fabric 1.21.11 client mod that detects blocked words and spam in chat, alerts you on screen, saves evidence screenshots, and logs flagged messages with usernames and timestamps.
About this Mod
Moderation Log Tool is a client-side Fabric mod for Minecraft 1.21.11 that helps you track abusive or suspicious chat in real time. It watches incoming messages for blocked words, slurs, sexist abuse, suicide-incitement phrases, and spam from players repeating the same message multiple times. When something is flagged, the mod can show an on-screen alert, save a cropped screenshot of the chat area, and write a detailed TXT log with the player’s username, timestamp, reason, latest message, and recent message history.
It also includes an in-game moderation menu with a Minecraft-style UI, a rebindable keybind, live session tracking for flagged players, editable blocked words, and configurable alert/screenshot settings. The blocked word matcher also catches many common spaced-out, punctuated, and leetspeak variants, making it harder for players to bypass the filter.

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Moderation Log consumes the most tick time.
