I was surprised how hard it was to get a good spam filter for WordPress. I tried two other plug-ins that had massive download counts and 4.5 ratings before WP-SpamFree and was not happy with either. I had setup a wordpress blog for my 60 year old mom and she was deluged by 850 spam comments in one day. She was a bit flustered and called me at work. Today she can wake up to a spam free day. Thanks a lot for your work on this.
