I hate reCaptcha as much as you. However, theymos made a poll back in October asking users
"What do you think of the forum's usage of reCaptcha?" and nothing has changed since them.
I probably won't make changes in the near future, but I've been thinking about the captcha issue, and I wonder what people think about reCaptcha.
Where reCaptcha is used now, something is required, and AFAIK all other captcha services can be OCRed and are therefore useless. End-users often like SolveMedia, but those seem really easy to OCR. I actually really like the image classification approach on a theoretical level, though I hate relying on NSA-lite Google, and occasionally on Tor they throw you into some insane black hole of difficulty (though you can change your Tor exit to fix that).
Same here, I didn't like the recaptcha because it's a bit annoying. We should choose the right picture every time to be able to login in a bitcointalk account. The problem with it, that sometimes it's not well shown, so I make some mistake to choose the right pictures, In result I will fail to login. I don't know the real reason of it, but we should use the right navigator to able to solve the captcha very fast.
