AskBot should probably support a question-based captcha, for instance on this website "What's the colour of the top bar?". Usually spambots don't bother resolving manually the captcha questions which require context and/or are only useful for a small site. In our experience with thousands MediaWiki wikis, QuestyCaptcha is the most robust solution.

ReCAPTCHA was broken years ago by spammers and NoCAPTCHA still ends up annoying users with questions which are easier for a bot than for a human.
