reCaptcha on Polar Rose blog

Friday, July 13th, 2007

Like most other blogs this blog has been heavily attacked by blog-spam. Akismet has done a fair job keeping most spam out (48,491 and counting as of today), but some was still making it’s way through.


The next obvious step was to install a captcha solution and as you’ll see at the bottom of this post, we’re now using reCaptcha.


reCaptcha was conceived by one of our very biggest heroes here at Polar Rose, namely Luis von Ahn, assistant professor at Carnegie Mellon University and father of the fantastic ESP Game (licensed to Google as the Google Image Labeler).


Along with stopping spam, reCaptcha helps the Internet Archive digitize parts of books that could not be automatically OCR’ed.


So keep those comments coming!


PS. I wrote more about reCaptcha on the O’Reilly Radar team blog where I also post.
