Captcha the spammers!

Tammy emailed me today with the following news:

Hi!

I usually find lots of interesting links on your website, but today I have one for you…
http://recaptcha.net/learnmore.html

a freebie from Carnegie Mellon University…

What a great tool… you get to prevent spamming on your website, and we help them to digitise books (where the OCR hasn’t recognised the word properly).

Ciao from Sydney,
Tammy

reCAPTCHAI have had the problem of spammers lately – over the past 3 days I have received 137 spam comments on my blog! I do have a spam utility that helps filter them, but I still have to go through them to confirm that there isn’t a post that has accidentally been flagged as spam (which happens once or twice a week).

I had noticed on Blogger that there is the option to get users to enter in random words – and I had always wanted something like that on my blog. Now there is this free tool!

What Tammy means when she says that “we help them to digitise books” is that Carnegie Mellon University is currently involved in “multiple projects [that] are currently digitizing physical books that were written before the computer age” (read more by clicking on the link or image above).  This involves scanning and Optical Character Recognition (OCR) which doesn’t always accurately read the characters. By entering in the words as you see them when you comment, you are assisting in proofreading these books!

And keeping my site free of spam! Even cooler! ;)

Thanks, Tam!
