“No-CAPTCHA” reCAPTCHA
Have you ever had to deal with spam on, eg, a forum or wiki? CAPTCHAs are absolutely necessary in many cases.

Yes. At PayPal we had one of the very first. And then at Eventbrite as well. They are most definitely overused.

Interesting. If I may ask, what alternate routes did you take to counter spam without resorting to CAPTCHAs?

Honeypots and timestamps would work in many cases. There are folks who want to captcha anything because they couldn't care less about users. But then when you take a step back and question if it's really necessary, it's frequently not.
