DNS-anti-spam is a plugin to protect your weblog from spam-comment. It checks the IP address the comment is posted from against a few blacklists, and checks the content of the comment against a huge list of known spammer websites.
How can I tell if it’s working?
What you could do is look in your email, pick a few recent spams, and pick the URL from them. Try to enter a comment with them. I just did that while typing this, and I was unable to enter “http://www.pokupki.net” in a comment.
- Upload to your plugins folder, usually
- Activate the plugin on the plugin screen
