What's the alternative to the recaptchas? Is the difference to just to use a different captcha service?



CAPTCHA is a divisive topic on HN, so you'll get a lot of people suggesting it's vital, and a lot saying it just isn't, depending on their own experiences.

"You probably don't need ReCAPTCHA" [0] is an article discussing techniques that has had decent discussion [1] on HN before.

Proof of Work is one that can help, but the HN crowd does not like those.
