Chat Filtering
Chat Filtering is a Minecraft mod that allows server owners to prevent players from using inappropriate or unwanted words or sentences.
Configuration
After installation, a config file will have generated at config/Chat Filter/chat-filter.toml. There you will find all the configuration there is available.
How it works
The mod has 3 different filters:
- Messages sent in chat
- Commands executed (
/say,/me,/tell,/msg) - Items renamed in an anvil
In first two cases, upon detecting a blacklisted word, the message in chat will not be sent or the command will not be executed, and the player will be notified. In the last case, the item's name will also be renamed to Inappropiate Name.
If in the config player punishment is enabled the player will receive a warning, and upon surpassing the customizable maximum amount of warnings, the player is punished according to one of the 3 available ways you can choose from in the config:
- The player is temporarily muted for a configurable amount of time
- The player is kicked
- The player is banned
The filter detects if the player is trying to camouflage the bad word, like adding spaces or punctuation in between and will still detect it, but it does not detect letter replacement, for example by numbers like in this example: h3llo instead of hello. Who configures the config must blacklist these mutated words as well.
