Detection Methods 1️⃣ Plugin Channel Detection This is the main detection method. When a player joins, FakeModBlocker checks the plugin message channels that the client registers. Many mod loaders and mods automatically register channels that can be detected by the server. 2️⃣ Optional Sign Translation Detection FakeModBlocker also provides an optional advanced detection module. It works by opening a sign editor with translation keys and checking whether the client translates them, which may reveal the presence of certain mods. Possible actions: NOTICE KICK BAN IGNORE ⚠ This feature requires server support for the sign editor API. If the current server implementation does not support it, FakeModBlocker will automatically skip this module safely. ⚠ Limitations FakeModBlocker is not a full mod detection or anti-cheat system. Limitations include: ✘ Cannot detect every mod or hacked client ✘ Some clients can hide their plugin channels ✘ Only works if the client exposes detectable behavior ✘ Not designed to replace an anti-cheat plugin ⚙ Requirements FakeModBlocker is compiled using Java 21.
