Spam—we all hate it and it’s not just for email anymore, hello Drupal comment spam.
To determine what is effective at preventing Drupal spam, I decided to run a little case study when I redesigned this site and the following are the conclusions I drew from trying a number of different combinations:
First, to enable Captchas you need the captcha module. Don't get fooled by the documentation stating it requires textimage module. It doesn't. Instead it serves simple, text based captchas. I personally prefer text based captchas over image based, since they are a lot less error prone, and they are accessible to (color)blind people, too. Additionally, as I will explain later on, image based captchas can as easily be bypassed as text based ones, so they don't provide additional security.
In an effort to prevent spam on your Drupal website, I've identified 10 modules built specifically for spam protection.

A CAPTCHA is a challenge-response test most often placed within web forms to determine whether the user is human. The purpose of CAPTCHA is to block form submissions by spambots, which are automated scripts that post spam content everywhere they can.
In order to have a higher search engine ranking, you need a lot of webpages outside your site with good articles linking back to your site. Now you can achieve this goal with w3courses.com by creating an account with W3Courses.com and posting your content as articles with a link back to your site at the bottom of each article.
