Blocking spam comments is one of the most essential practices to maintain a high quality to your WordPress blog. In this article, therefore, we’d like to introduce some effective strategies to prevent spam comments in WordPress easily. In fact, opening discussion makes your blog engaging and interactive, but not every visitor browsing your blog with a view to adding something worthwhile to the conversation. In this circumstance, you need to take some measures to stop these spam, random, or commercial comments that might devalue your WordPress blog.
Checking the comments manually is the most widely used and easiest strategy to prevent spam comments. You only need to log into your WordPress dashboard and point to the Comment section, scanning all the comments quickly. Once you find any worthless and meaningless comments, simply remove them at once with a single click. However, this strategy is a little bit time and energy consuming for some large and popular blogs with a tremendous number of page views each day.
Utilize Verification Code
Many spammers leave the spam comments on your blog by some certain kinds of robots. Therefore, you can insert a validation form prior to the comment publishing, verifying that the comments are submitted by real people but not a spam. Commonly, the verification codes are generated by CAPTCHA technique, consisting of customarily misaligned and distorted content.

Make User Registered
This strategy has been utilized by many bloggers. People must be registered to your blog, thus get the allowance to leave some words in your comment section. Always remember that spammers wishing to increases their website’s search engine ranking by leaving spam comments to thousands of hundreds of websites will not spare even 1 second to register to your blog site. Instead, they will immediately target some other blog sites that have no registering requirements.
Ban IP Address
Another spam comment prevention measurement relies on whitelists and blacklists. For some malicious IP addresses that generate spam comments, you can ban them constantly from posting anything to your blog site. Once spammers try to make a comment with the same IPs, they end up getting a custom message informing that they are not allowed to comment this blog anymore.
Disallowing Some Certain Keywords
In order to increase the number of potential visitors and customers, spammers always post spam comments with the backlinks to their websites and some keywords containing the names of their products or services. In this respect, you can block the spams by banning these keywords effectively. To be honest, this can be seen a long-term resolution as it is not beneficial for the spammers to change the keywords thus getting the comment posting allowance.
Block Links in Comment Posting
Disallowing the links to be contained in the comment posting is also able to prevent spam comment effectively. Spammers always include the links that lead to their own websites to get higher rankings. Therefore, if your blog does not allow links in the post, they will unable to leave any comment on your site.
Utilize Spam Prevention Technology
Many spam prevention technologies focus on finding out whether the commenter is a human being, thus is very likely to irritate the wrong crowd like your loyal readers. Here, we highly recommend Honeypot – a powerful technology creating fake testing for the robots, instead of giving a challenge to human visitors. The testing will trap the spam robots into revealing themselves before they could post spams and this testing will not be seen by real readers.
To enable this technology, you can consider the utilization of the WP Spam Fighter plugin. This tool can prevent the spam comments effectively without needing you to make the moderation for all the comments. Even, your readers can pass the process of answering the stupid arithmetic questions and just finish the simplest CAPTCH process.
From the settings page, you can start the timestamp protection, honeypot protection, ReCAPTCHA protection and other spam blocking methods.
Note that unlike many other techniques that figure out whether a user is a human being, Honeypot finds out whether a user is a robot. In this case, it will give the challenge to the bots but not your real visitors. This means when the Honeypot protection enabled, this plugin will add a hidden form field into the comment section of your site. This filed can only be seen by bots to filter them out.
The Utilization of Akismet Plugin
In fact, when it comes to prevent WordPress spam, the use of the Akismet is one of the most effective methods. The proper utilization of it requires you to get an exclusive API key. You can get more information from this Akismet user guide for your WordPress site.
What you need to know is that this plugin will check your comments automatically and filter the suspicious, bad and spammy ones before the comment pending process.
