BlockReports

# BlockReports Plugin **BlockReports** is a Minecraft Paper 26.2 plugin that prevents chat reporting by neutralising Minecraft's chat signature system and blocking report-related functionality. It also works around client-side chat blocking (like how the UK stops some accounts from chatting) by providing command-based chat, private messaging and emotes that still work for affected players. Although it was custom built for [minecraftoffline.net](https://www.minecraftoffline.net), any server can use it. ## Installation 1. Download the latest release [here](https://github.com/Jelly-Pudding/BlockReports/releases/latest). 2. Place the `.jar` file in your Minecraft server's `plugins` folder. 3. Restart your server. ## Features * **Strips chat signatures** - Converts signed chat messages to unsigned system messages which makes reports unverifiable. * **Bypasses client-side chat filters** - Renders chat as `name: message` rather than ` message` which prevents the client-side "friends only" and blocked-player filters from hiding messages between players who aren't friends. * **Hides warning popups** - Eliminates the annoying "Chat messages can't be verified" popup for players. * **Neutralises chat sessions** - Intercepts chat session update packets and replaces public keys with null values to prevent secure signature establishment. * **Prevents chat-related kicks** - Stops players from being kicked for signature validation issues. * **Automatic server configuration** - Disables `enforce-secure-profile` in server properties (this setting forces players to have signed profiles to join). * **Works around client-side chat blocking** - Some accounts are blocked from chatting client-side (for example UK players will see a message such as *"Sending chat messages is not allowed"*). For these players, there is a `/chat` command (alias `/c`) that sends a normal (unsigned and unreportable) chat message. Since a blocked account can't be detected server-side, the `chat-command-hint` configuration option shows a `/chat` hint on join to any player who hasn't sent a message yet. * **Private messaging for blocked players** - Vanilla `/msg`, `/tell` and `/w` do not work for players with chatting blocked client-side as they carry a signed message argument so BlockReports provides its own `/msg`, `/tell`, `/w`, `/t` and `/r` commands that work for them. An unsigned `/me` emote command is also provided for the same reason. * **Lightweight and efficient** - Minimal performance impact with targeted packet manipulation. ## Commands * `/blockreports reload` - Reloads the plugin configuration. * `/chat ` (alias `/c`) - Sends a chat message via a command which bypasses client-side chat blocking. * `/msg ` (aliases `/tell`, `/w`, `/t`) - Sends a private message. Works for players blocked from chatting unlike the vanilla command. * `/r ` (alias `/reply`) - Replies to the last private message. * `/me ` - Sends an emote/action message. Works for players blocked from chatting. ## Permissions * `blockreports.admin` - Allows use of BlockReports commands. (Default: op) * `blockreports.chat` - Allows sending messages with the `/chat` command. (Default: true) * `blockreports.message` - Allows using the private message commands. (Default: true) * `blockreports.me` - Allows using the `/me` emote command. (Default: true) ## Configuration The plugin creates a `config.yml` file with the following options: ```yaml # Strip chat signatures from outgoing chat packets. # This converts signed chat messages to unsigned system messages. strip-server-signatures: true # Hide the secure chat warning popup. hide-secure-chat-warning: true # Neutralise chat session update packets from clients. # This intercepts incoming chat session packets and replaces the public key with null, # preventing secure chat establishment while maintaining proper packet flow to avoid kick issues. neutralise-chat-sessions: true # Prevent kicks related to chat reporting. # This handles various kick scenarios related to secure chat. prevent-chat-kicks: true # Provide a /chat command (alias /c) for sending messages. # Some accounts are blocked from chatting client-side (for example players in the UK). # /chat is sent as a normal (unsigned and unreportable) chat message. enable-chat-command: true # Hint players about /chat on join (until they send their first message). # Useful for players blocked from chatting client-side. chat-command-hint: true # Enable debug logging - only enable this for development # as it's verbose. enable-logging: false ``` ## How It Works BlockReports operates by: 1. **Intercepting outbound chat packets** and removing cryptographic signatures. 2. **Pretends the enforce-secure-profile flag is true** in login packets to prevent client warnings. 3. **Neutralising incoming chat session updates** to prevent signature key establishment. 4. **Converting signed messages to system messages** that cannot be reported. This approach ensures chat reports become unverifiable and ineffective while maintaining full chat functionality. ## Support Me [](https://ko-fi.com/K3K715TC1R)
