Nuts. Over the last two days my inbox has started filling up with spam comments here on the Codeunit blog, and naturally something needed to be done, and pretty quickly at that.
Which is exactly why I slapped in place the ReCAPTCHA CAPTCHA challenge on my comments pages, replacing the older and rather ineffectual digit challenge system that was there in the first place.
I’ve known about the ReCAPTCHA project for quite some time now, and it is actually quite a clever workhorse in that its main goal is to help transcribe books, by using us humans to work out the words that modern OCR applications can’t seem to make out. What I did however not know was just how easy it is to set up in one’s code, so hats off to the developers for making this such a painless task!
Oh, and just as an aside, ReCAPTCHA sports a pretty nifty audio CAPTCHA component as well, making it a breeze for even visually-impaired people to get through the system.
Which should come in pretty handy one day considering the rate at which my eyes seem intent on deteriorating!
Anyway, this should now halt the spam if it is being computer generated, but if not, well I guess I’ll just have to think about comment moderation then.
Stupid spammers and con artists!
