Post inspired by the bot threat that people on Lemmy have been talking about. I’m not asking how an expert would design it, but how you would design it if you were tasked with it.

    Captcha or recaptcha is good enough imo, no point in reinventing the wheel. Alternatively, split instructions in an email and on the website. For ex: Send email with What is the square of 3 (sent as an image for every word) And on the website Email + 25 = xxxxx

      Captcha or ReCaptcha are easier to solve for the bot I use to solve it for me, than it is for me…

      Your 2nd idea is trivial to solve for any specialized bot.
