Am I a human? Yes. Can I type phi off the top of my head? No.
According to reCAPTCHA:
Each new word that cannot be read correctly by OCR is given to a user in conjunction with another word for which the answer is already known. The user is then asked to read both words. If they solve the one for which the answer is known, the system assumes their answer is correct for the new one.
So therefore if nobody else figured out this one, you would be the first and you could legitimately type anything and succeed at it.
Pfft... that's easy. Try this one:
As promised, here's the one I got a few days ago:
Edit: One more from just now (looks like they are scanning math books):
This is a trick question: you fail if you can type it.
The cat and mouse game continues...
Remember that, if the challenge is too "hard" to solve, you can request a new one with the "refresh" button.
Readable, just confusing. It seems like reCAPTCHA is now digitising house numbers on Street View as well ;)
You misunderstood - you are supposed to solve the equation as well.
I know it's tough but we have to keep the cyborgs out of Meta.
Now, isn't at least one of these supposed to be a real word?
(or use LaTeX
I actually got 4 Greeks in a row. Sharing my favorite for posterity:
First of all, I am human but no human being can decipher the ReCAPTCHA I just encountered.
This is the best (or worst) CAPTCHA I've recieved.
I just got one with an integral from -∞ to ∞. Is reCAPTCHA digitizing math books this week?
I would have entered ompx.
You can also just press F5 to get another one.
I think it is the symbol of diameter. Well... I can: ∅ and ϕ
This are some details of phi:
UTF-8: 0xCF 0x95 UTF-16: 0x03D5 C-form (octal escaped UTF-8): \317\225 XML-form (decimal): ϕ
Distorted text CAPTCHAs can be a little stressful also!
