One of the fun things with blogs is the possibility for readers to post comments. Unfortunately spammers post spam comments just like they send spam e-mail. So to keep the possibility for real visitors to post comments we need some type of defence against spammers.

The ratio of spam in comments is about the same as for e-mail. Something like 7 or 8 out of 10 is spam.

In an effort to stop comment spam xdeb.org has used the Captcha module with a simple math captcha.
