CMS Made Simple Forums

I have a website using the News module with the Feedback module for comments. I have Captcha installed, but there is still a lot of manual spam that arrives in my mailbox that I have to take time to delete before I post those comments. Is there anything else that is available to prevent spammers from trying to add their crap as comments to the news articles? I've looked through the modules list, but didn't find anything that stood out as an "anti-spammy" resource. Or does anyone know of any other tricks I could apply to help the situation?

I bet most of the manual spam has http://... links. So, some sort of filter to reject a message if it includes http:// ? And show an error message in case a real person includes a link in a comment. Not sure how to implement that though...

akismet should still work with CGFeedback.

Thanks paulbaker and calguy - I'll check those suggestions out.
