As you noted, most captchas are crackable. This is the reason we have decided not to implement one. It's common thought that captchas reduce spam -- which they do -- but they do so by reducing total signups (human and robot).
Personally, I'd rather deal with spam in craftier ways than prevent legitimate people from signing up.
- hyyypr 17y agoThanks for replying. But I have a hard time understanding how filling a captcha can make people willing to signup run away. Either you're offering a lightweight service with one single and simple functionnality (like instapaper.com for instance, which only requires a username for registration (not even a password !)); either you offer a multi purpuse service like github and if someone begins the registration process on a site like this and runs off because he doesn't want to fill a captcha.. maybe it's better he doesn't register after all. Anyway what I really want to know is your numbers and how you got them :)
