I checked out the registration form for a white

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.
