Suppresses join/leave broadcasts for players who relog too frequently.
Silence the noise. Keep your chat clean.
Stop join/leave message spam dead in its tracks — with zero player impact.
AntiJoinSpam is a lightweight, high-performance server plugin designed to eliminate the chaos of repeated join and leave message spam. Whether it's a player with a flaky connection, a bot cycling through reconnects, or just someone rage-quitting and rejoining, AntiJoinSpam automatically detects and suppresses the clutter — keeping your chat readable and your players happy.
No commands to memorize. No permissions to configure. Just install, tune your config, and let it work silently in the background.
AntiJoinSpam is built to coexist peacefully with any plugin that manipulates join or leave messages. It hooks into the event pipeline after other plugins have had their say, meaning your custom join messages stay intact — they're just silenced when spam is detected, not replaced or broken.
Confirmed compatible with:
| Plugin | Notes |

| CMI | Full compatibility with CMI's join/leave message system |
| LuckPerms | Works alongside prefix/suffix-based join messages |
| AuthMe / NexAuth | No interference with login-gate plugins |

If a plugin fires a custom
PlayerJoinEventorPlayerQuitEventmessage, AntiJoinSpam will suppress that message — not override it. Your formatting, prefixes, and placeholders remain untouched.
