I have a couple of WordPress Blogs as Hosted Sites and have been getting killed with Comment Spam. I installed a new Plugin today to see if that helps.
I am using the Growmap Anti-Spam Plugin on another blog, and that worked really well for awhile, but it appears there is a work-around for the Spammers, and now I am getting swamped again on that blog.
I am trying the “Spam Free WordPress” Plugin for this site to see if it is effective.
Growmap is rated 5 stars, and Spam Free WordPress is only rated 4 stars, so we’ll see which one works best.
