The ChatFilter plugin provides a configuration file that allows you to customize its behavior. Here are the key settings you can modify:

• prefix: Specifies the prefix to be used in filtered messages.
• rejected-message: Defines the message that a player receives when they write a forbidden word.
• show-message: Determines whether the filtered message should be shown in the chat or not.
• forbidden: Contains a list of forbidden words or phrases.

To customize the plugin's behavior, simply modify the values of these settings in the configuration file. Restart the server for the changes to take effect. Please note that the § symbol is used to format text color and style in Minecraft. Make sure to follow the proper formatting conventions to achieve the desired display in the chat.
