    What the heck? I just got hit by a captcha request while answering a question. I was logged in as me, a fairly long standing user. This ain't right, is it?

    If SE thinks you're a robot, you get hit with it. I get hit with it all the time. Do not worry. You... can... still... learn... how... to... love... (*ceases functioning*).

    I very regularly get captchas while logged in. I have no idea why this is, but it's not because of anything unique you did.

    I console myself with the thought that at least I'm helping to improve OCRing.

    I get this whenever I do a lot of things quickly: commenting on a lot of threads, posting answers/questions, etc. Even if you stick with the time limit, if you do a lot at once, the software seems to think that you might not exist.

    I usually get the captcha when I do things quickly (like edit a post several times, trying to take advantage of the five minute window), but apparently you also get a captcha if you take too long. This has been "corrected" on S[OFU], so it should be fixed on MO once changes from S[OFU] are merged into SE (after it's out of beta).

    Hmm. Odd that I hadn't seen it before. I am not exactly a newcomer on MO, though I am not the most active either. In this case, it had been three hours since my previous activity, and I don't think it took me long to type in my answer either. Anyway, now that I know I am not alone in facing captchas, I'll stop worrying about it.

    I would feel so much happier if we were helping to OCR mathematical texts instead of the New York Times.

    I just got these two captcha's recently:

    here

    here

    I would be only too happy to help OCR mathematical texts, but recaptcha doesn't allow entering LaTeX :)

    I've noticed recently on the mathjobs wiki that math was appearing quite often in their captchas. (I've been spam-patrolling a bit there.) I just enter some LaTeX, and it mostly seems to work.

  8.  

    I was assuming that the recaptcha people are expecting plain text and not LaTeX code to be returned for the things they are OCRing - you're right though, entering LaTeX shouldn't cause a problem to the user.

    a captcha that requires entering LaTeX. Now that would weed out the trolls.
