MoMoTextFilter
by MoMoCraft
MoMoTextFilter is a Fabric social mod that screens chat messages against a list of banned words, with several matching methods and alert levels.
What it does
The filter checks each chat message against a configurable list of banned words. Matching is not limited to exact spelling: it can use a whitelist, match words written in reverse, and catch fuzzy variants where letters are swapped for look-alike characters. A mapping table covers confusable characters from Traditional Chinese, Japanese, English, numbers and punctuation. Cross-message detection can also link fragments sent in separate messages within a configurable range.
The mod can punish a player who uses a banned word, and it can send chat bar alerts at different levels for each banned-word entry. Custom commands are easier to add than before, because the command listener was rewritten. The anvil naming character limit has been removed, and the core logic was refactored. Interface text supports internationalization. The mod is open source under the GNU General Public License v3.0 only, and its source code is public. It is published for Fabric for game versions 1.21 – 26.1.2, and it also runs on Paper, Spigot, Bukkit, Purpur, Folia and Velocity servers.
