[NSFW] Stopp Words for Captcha Text?

Thanks for your plugin! If you have something like stopp words for your captcha text, it would be a good idea to add also some German words. Today we saw the captcha text: “HURE” (means bitch in German) under our form. This is not optimal to be trustworthy when someone wants to send the form with such words ?? Thanks again for your community efforts! Best, Steffen
