I've just attempted to post a question on Unix&Linux Stackexchange. I was prompted with a CAPTCHA with a picture of HAL 9000 and the following text:
Human Verification Are you a human being? We apologize for the confusion, but we can't quite tell if you're a person or a script. Please don't take this personally. Bots and scripts can be remarkably lifelike these days!
Check the CAPTCHA box, and we'll be out of your way.
There is no link, no CAPTCHA and no way to actually post the question. I'm not sure what's going on here.
I'm not surprised that I am being prompted to pass a CAPTCHA, my browser is atypical and so may appear like a bot.
Does stackexchange use Google for their CAPTCHAS?
