Where’s the Integral Sign?

This reCAPTCHA code is getting harder and harder to fill in. Found this in my comments section.

So …. does it want me to solve for x?

  • Only one of reCAPTCHA words is a real check to see if you are human. One is allowed to be pretty much anything you want because it is not yet “set.”
    I don’t know which one it is, but it is possible it would have worked by typing in “XXXX labinco.”
    I wonder if this can be exploited by organizing a series of consistently misspelled words to poison the reCAPTCHA DB with bogus words?
    But still, lucky you can ask for another pair.
