Your great Drupal blog is begining to receice traffic. With the traffic, comes comments. Some of them are legitimate, but most of them of a spammy nature.
Of course, you can shut down all comments and use use facebook comments instead but this won't give you any SEO value, since the comments are stored in facebook. And what if your client base is using another social network such as twitter or Linkedin? Outsourcing the comments to social networks is not a real solution. So How to stop spam in Drupal websites?
One better way is using the Mollum spam protection service, which is free for personal blogs, small community and non-profit sites. Mollum is cross-platform - so you can also use it to treat Wordpress spam. In fact, mollum is a great free alternative to the built-in akismet plugin which is not really free:

But Mollum is only an anti-spam solution. Today, what we really need is a total SEO-friendly comment management solution, which includes moderation features, social connectivity, and analytics.
Here Disqus is the best option - see the crowd wisdom:
With connection to all major social networks, Disqus gives you better control. For example:
The ability to edit comments on your blog is priceless, especially when dealing with quality comments that may ere too much on the vulgar side (or post sensitive information that needs to be removed). (Disqus vs Facebook Review)
