It is always recommended that you follow the server rules.**\n\n## The Vulnerability\n\nMinecraft has a feature that allows text (in chat, on signs, or in the bossbar) to be specified by a keybind the user\nhas set, or a translation key. The Client will then replace the translation key, or the keybind with the stored value.\nThis can be abused by the server by serving the client a sign with such a placeholder (for example Sodium:\n`sodium.option_impact.low`). By immediately closing the sign screen, the client sends the edited text to the server\nwithout ever seeing a sign open screen. The server can then detect wether you have that specific mod installed, by\nchecking if your client replaced the placeholder with the corresponding text (`sodium.option_impact.low -\u003e Low`). If\nyou don't have Sodium installed, the placeholder will stay there\n(`sodium.option_impact.low -\u003e sodium.option_impact.low`).\n\nThis also works on the Anvil screen. The server could prompt you to open the anvil screen, with an item in the\nrenaming slot that has a translation key as it's name. The client would then rename the item to the corresponding\nvalue and send an update to the server. (Huge thanks to Frog, `@croaak` on discord, for figuring this out)\n\nThis detection method works for any mod that has custom translations.\n\n## The Fix\n\nThis mod fixes this issue by simply not resolving any translation or keybind placeholders on signs, except vanilla\nones. This makes it impossible for the server to use this method to detect installed mods.\n\nTo verify this works you can test it in a [test world](https://github.com/JustAlittleWolf/ModDetectionPreventer/raw/1.20.4/testWorld.zip).\n\n## Intentions\n\n~~While this feature can be used to prevent harm by detecting cheaters early, it is implemented improperly on some\nservers, including [Cytooxien](CytooxienDetectedMods.md). Immediately banning players upon joining, simply because they\nhave tweakeroo installed, is unacceptable.~~\nAfter a discussion with the developer of Cytooxien, they told me that players won't get banned for using tweakeroo, only kicked repeatedly.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjustalittlewolf%2Fmoddetectionpreventer","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fjustalittlewolf%2Fmoddetectionpreventer","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjustalittlewolf%2Fmoddetectionpreventer/lists"}
