Thread:Talk:CAPTCHA/Bauernegro - What system are we using!?

I work quite extensively on several different Wikipedias, and CAPTCHAs are normally only a minor nuisance for me. I was importing templates to the Zulu Wikipedia when I was met by the CAPTCHA code BAUERNEGRO. What is this? Are we not applying any filtering at all on the words we use? This was after already being prompted to write gipsydick. This is extremely offensive, and not acceptable from a major website like Wikipedia or from MediaWiki.
