See https://codex.bbpress.org/moderation-and-blacklisting/

The above document outlines the different behaviours between adding the ‘bad word’ to the ‘blacklist’ or ‘comment moderation’ sections and what the users see, in the next release of bbPress there will be a notice if the ‘bad word’ was added in ‘comment moderation’ and the user will know that there submission is pending moderation, the blacklist behaviour will not be changing.
