to add to the chat filter you would use $filter + <filtered word>
likewise to remove, you would use $filter - <filtered word>
nypsi is a bit unique and uses a ‘percentage matching’ algorithm to attempt to catch people trying to sneakily evade filtered words. it isn’t perfect and will take some tuning to get right for your server. note that this only works on words in the chat filter that are one word, meaning they don’t have a space character.
to change the percentage match, use $filter match <percentage>
use $filter match 100
to only filter exact matches.
you can test the filter with $filter test <phrase>
, this will allow you to easily test and perfect your percentage match
