The Frick-Web site has been getting a lot of blog comment spam in the last days, but no longer. I integrated an akismet anti spam plugin which was developed originally from Ryan Bates. This plugin uses the akismet web service to check if a comment is spam or not. You can find the plugin here [LINK].
Ryan Bates did a railscasts about this plugin a few years ago. So just check it out, i think it is very useful and really easy to integrate into a rails application. Just follow the railscast and your blog is free of annoying spam attacks from now on.
