Disabling chat reporting
Note: In 1.19.1, Mojang introduced chat reporting. Some players prefer this feature to be disabled so conversations remain moderated solely by the server rather than by Mojang.
Steps
- Download the plugin: https://www.spigotmc.org/resources/no-chat-reports.102990/
- Put the
.jarfile into your/pluginsfolder. - Restart the server.
Chat messages are now unreportable and Minecraft chat reporting is effectively disabled.
