The best advice that I can give people who "remember" seeing something is to use
Google to search for the information.
We have had this discussion before and there are four important points that I would like to make:
1) The was a configuration option in
Fireboard (and therefore in K 1.0) about 6 years ago to integrate a third party-developed plugin that achieved some "bad" word filtering. This option was removed in K 1.5 — that is, in June 2009. There was never any badword filter feature created or fully supported by the developers of
Fireboard or
Kunena.
2) I am not aware of any discussion forum software that has a bad word filter feature built into the core component. For those discussion forum software products that may have the facility to filter out bad words, this is usually done as an add-on; this is not usually done as a core function of the forum software. Most "bad word" problems are problems of bad behaviour that are usually resolved by effective forum moderation and by having a well-published
terms of use
policy.
3) There is no bad word "feature" in K 3.0. See
Kunena Features
.
4) The project team has no plans to develop a "bad word" add-on for
Kunena. See
Feature Request: Integrated Badwords filtering
. There
may be other, third-party tools that will achieve the same result (e.g.
Badword2 - myth or it really works?
) but, because I have not seen any discussion on those ideas for four years or more, I really cannot say.
While it may be possible for someone to write a plugin that will work with
Kunena to replace "bad words" with some other text, I am not aware of what plugins may exist, who has written them or how you would obtain them.
In summary, you may search in the
Kunena configuration settings for K 3.0 but you will not find any "badword" option. If you would like to search further, I suggest you use
Google. I hope this answer your question and will help anyone else who may be interested in this subject.
Good luck.
