CAPTCHA-like task that requires a couple of minutes to complete
August 11, 2013 1:11 AM Subscribe
I'm looking for a CAPTCHA-like service (e.g. ReCAPTCHA). However, it needs to be one that requires more time & effort to complete, since my goal is actually to create a barrier to entry for my site (i.e. have users prove that they are competent and willing to invest effort). Like transcribing entire paragraphs of text, rather than just a couple of words, or solving some sort of puzzle. Does anyone know of such a service, ideally one I could easily plug into my site?
