Hi, I wonder whether a strength-in-unity-in-diversity approach might work best for captchas in allowing each site using Mediawiki to easily choose its own set of alternating questions-and-answers (and allow them to be changeable) for a registration captcha. If spammers get around to being able to parse any human language, I'd guess the could be making better money using their tools for other purposes... :)
Sounds like already part of ConfirmEdit extension as QuestyCaptcha.
Yes, I subsequently found this, thanks! (I'm marking as resolved/invalid, though I don't know whether others might want this built in rather than as an extension.)
