📖About FakeModBlocker

🧩 FakeModBlocker

A lightweight, fully customizable, and cross-version friendly mod detection plugin that monitors plugin channels to identify some mods like Xaero's World Map, Replay Mod, and known mod loaders such as Fabric, Forge, and more.

It also supports an optional advanced sign translation detection module on supported server implementations.


✨ Features

✅ Lightweight — zero unnecessary overhead
✅ Fully customizable messages and behavior via messages_xx.yml
✅ Hex Color Code support for 1.16+ servers (e.g. &#00ffcc)
✅ No dependencies — drop-in and go
✅ Works across a wide range of server versions (1.8–1.21.11+)
✅ Multi-language support (en, cn, and your own language)
✅ Reload support: /modblocker reload
✅ Spigot / Paper / Purpur / Folia / PandaSpigot support
✅ Optional advanced sign translation key detection on supported server APIs


🔍 What it Detects

FakeModBlocker primarily detects clients or mods that register known plugin message channels, such as:

  • fml:hs → Forge
  • fabric:registry/sync → Fabric
  • xaeroworldmap → Xaero's World Map
  • Any custom channel you define

In addition, FakeModBlocker also provides an optional sign translation detection module for certain mods that expose identifiable translation keys.
This advanced detection is configurable and can apply actions such as:

  • NOTICE
  • KICK
  • BAN
  • IGNORE

🧠 Detection Modes

1. Plugin Channel Detection

This is the main detection method and works across the widest range of versions.

It checks which Plugin Message Channels the player is listening on when they join.
Many mod clients (e.g. Fabric / Forge and some utility mods) automatically register custom channels, which this plugin can detect and respond to.

2. Optional Sign Translation Detection

This is an extra optional detection module.

It works by opening a sign editor with specific translation keys and checking whether the client translates them, which may reveal the presence of certain mods.

⚠️ This feature depends on server API support for opening sign editors.
If the current server version / implementation does not support the required public API, FakeModBlocker will automatically disable this feature and skip it safely.


⚠️ Important Notes

⚠️ FakeModBlocker does NOT detect all mods or cheating tools.
It only works when the client exposes something detectable, such as known plugin message channels or supported translation-key behavior.

⚠️ This plugin should NOT be treated as a full anti-cheat or universal mod detector.

⚠️ The optional sign translation detection is an additional enhancement, not the main detection system.

This makes FakeModBlocker ideal for detecting casual use of mod loaders or certain utility mods, but it should not be treated as a complete anti-cheat / mod-blocking solution.


📂 Installation

  1. Drop the .jar into plugins/
  2. Start the server to generate config files
  3. Edit config.yml and your language file
  4. Use /modblocker reload to apply changes instantly
  5. Some mods are pre-configured in config.yml, and you can freely modify them to match your server rules

⚙️ Compatibility

  • Main plugin channel detection is designed to be broadly compatible with 1.8–1.21.11+
  • Optional sign translation detection requires a compatible server API
  • On unsupported versions / server implementations, the sign detection module will be disabled automatically
  • Folia is supported through compatible scheduler handling

❓ FAQ

Q: Can this detect hacked clients like Vape or LiquidBounce?

A: No. Those clients often avoid using detectable plugin message channels. This plugin is best used to detect mod loaders like Fabric, Forge, Lunar, etc., and some configurable translation-key based mod detections on supported servers.

Q: Is this an anti-cheat?

A: No. This is a mod presence detector, not a cheat detection system.

Q: How does it work?

A: Its main method is checking which Plugin Message Channels the player is listening on when they join. Many mod clients automatically register custom channels, which this plugin can detect.
Additionally, on supported server APIs, it can optionally use sign translation key detection for certain configurable mod signatures.

Q: Does the sign detection work on every version?

A: No. The sign detection module depends on public sign editor API support (Sorry i don't have much time to test every single version, but it should work on every Paper server i guess). If the server does not support it, FakeModBlocker will automatically skip that module without breaking the plugin.
