But on the other side, it needs to be understood just how important having a CAPTCHA is. The amount of destruction to user experience that bots can cause is sometimes far worse than the pain the CAPTCHA causes. The long chains of reCAPTCHAs annoy me to no end, and I hope a middl…
What exactly do you mean by computational challenges? That seems like the exact kind of thing a bot would be much better at compared to a human.
In some scenarios such as spam, the profit per bot action isn't high at all, so this might be feasible. If it's a ticket bot, that wouldn't work at all.
