Forget Spam Comment is a free WordPress anti-spam plugin you can use to get rid of automatic comments posted by bots on your website. All you have to do is just install it and then leave it on its form and it will take care of all the spam. The best part is that it does not add its own commenting system rather it works with the built-in comment system of WordPress. It is GDPR-compliant as well and it will work on almost all kinds of WordPress websites.
Basically what this plugin here does is identify whether a comment is posted by a human or bot. It detects the site interaction behavior by the current visitor and then decides the spammy behavior. If you want to know more technical insides then know this that here it blocks the default action path (wp-comments-post.php) for bots and make it accessible over unique hash query string when an actual visitor scroll to post a comment.
Another advantage which this plugin has is its fast speed and very low size. The entire script that injects in your website is just a few kilobytes.
