Found this post in a search because I was having issues with the Antispam filter blocking words such as a certain male body part, when I did not check ANY of the dictionaries nor did I have anything listed in the ban words text space.

Since the UNA devs do not wanna specify where these default words are, or the words contained in the dictionaries, I have done the research and located them in here "/plugins/snipe/banbuilder/src". No modification needed to review these words.

class BxAntispamProfanityFilter extends BxDol
{
    protected $oProfanityFilter = null;
    protected $sPluginPath = BX_DIRECTORY_PATH_PLUGINS . 'snipe/banbuilder/src/';
    
    public function __construct()
    {
        parent::__construct();
        
        $sClassName = 'Snipe\BanBuilder\CensorWords';
        $this->oProfanityFilter = new $sClassName;

Upon testing, it seems that en-base is being loaded in regardless if the box is checked or not in the Antispam Module settings.
