I think that the Captchas on the Programmers Blog are a bit too difficult to do. This may be a good thing if you are trying to prevent comments (sarcasm, did not think I needed to say it but question was edited to mean the opposite), cannot understand the words on many of them. Plus, the form is not re-entrant (meaning if you get the captcha wrong you lose what you wrote unless you go back in browser - and in the future someone does not add the header to not cache or whatever browsers want to not keep the previous page(s).

Can we fix this? A good captcha would be some of the new ones I have seen that ask you a question and you need to choose one of four, or even a home grown one with varying font style and sizes, plus random noise (lines, dots ...)

    I changed the reCaptcha theme from "red" to "clear". That might help. There aren't, at present, any other options for comment spam prevention.

    btw the CAPTCHA should go away if you log in, and you can log in with the same credentials you use for Programmers. It's not a perfect solution for unparseable CAPTCHAs, but it's a good enough workaround.

    alas @yannis-rizos you see the world with your filters. for us lesser mortals a mere login dont make the catch go away. it stays till we earn our stripes (more rep?)

  • Hm, you're right, I just logged in and the CAPTCHA is there. Perhaps it only goes away after you posted a couple of comments, and reappears periodically. I don't think reputation (or mod status) have anything to do with it.
