I checked out the registration form for a white supremacist forum, and they just use reCAPTCHA. No doubt they'll be developing a CAPTJCA or CAPTMCA soon enough.
There are likely a number of strings that should be added to the default blacklist. Patches welcome!
Yes, sites that want to screen out users with certain political, religious, etc. sensibilities could, with some small tweaks to the code, create a ConfirmEdit whitelist that causes *all* CAPTCHAs to contain words calculated to offend those groups. Actually, with QuestyCaptcha, this is already possible. One could include in $wgCaptchaQuestions answers that require the user to type in strings denigrating certain groups or deities; swearing allegiance to certain causes or entities; or stating that one has certain stigmatized attractions, preferences or desires or engages in certain stigmatized behaviors. One could also use it to screen for a certain level of intelligence, knowledge, etc. in a given field by asking questions only certain people would be able to answer. The possibilities are endless once one's main priority becomes to repel or screen out, rather than attract, most potential users.
