The Mollom service helps evaluate content quality, stop spam and lets you concentrate on building and improving your site. You can use Mollom for free, but you first have to install a plug-in on your website. This is really amazing. It works with almost all CMS software like Joomla!, Wordpress, Radiant, SilverStripe. It also available for Developer libraries i.e. java, PHP5, Ruby, Python, Perl, ColdFusion, .NET (1 & 2) & Zend Framework. What else? I think they cover everything.I am attaching a screen shot for Mollom statistics.
