Effectively prevent automatic spam when a spam comment is posted with Kama Spamblock, a plugin that operates discreetly and remains completely invisible to users—no captcha codes required. The plugin not only blocks spam comments but also conducts thorough checks on pings and trackbacks to ensure the authenticity of backlinks.
Even if you are using an external comment system like Disqus, installing Kama Spamblock remains valuable. This is because autospam can be posted directly to the ‘wp-comments-post.php’ file, and the plugin serves as a robust defense against such comments.
