As long as there has been the ability to leave comments on websites there has been spam. I recall creating a guestbook for a client once and even though the guestbook used a captcha it did not take long before it started to become overwhelmed with spammy comments. Fighting spam has become so difficult in fact that it can start to distract you from what you need to be focused on with your website in the first place, creating good content, attracting leads and making sales. If spam has become a constant battle with your WordPress website here are some ideas and tools that might help turn the tide on the battle.
Turn Off Comments
Depending on the purpose of your website you might not need or want comments in the first place. By turning comments off altogether your spam problem can be virtually eliminated over night. Even if you run a popular blog you can still turn off comments, much like Copyblogger did last year. I you do turn off comments altogether you might also want to add a redirect on the WordPress wp-comments-post.php file. Many spammers simply post to that WordPress file and never actually visit your website. By redirecting it using .htaccess or some other redirect you can simply send the spammer off to some location where they will do no harm.
Use Another Commenting System
There are several other commenting system that are available that can help cut down on the amount of spam you receive. Services like Disqus, Facebook Comments and IntenseDebate all offer the ability to host comments for you. Depending on your needs they might be just want you are looking for. They certainly can help in reducing the amount of spam your comments receive.
Use an Anti-Spam Plugin
If you do decide to keep comments on your website making sure you use a decent anti-spam plugin is essential. Many people will simply tell you to use Akismet, and while I would say Akismet is certainly a good plugin, if your website uses any ads or is for any kind of commercial use AT ALL then you should honestly stay away from Akismet unless your website has grown to the point of being able to earn enough money to be able to afford the Akismet monthly rates.
Thankfully Akismet is not the only anti-spam plugin available. Some of the more popular plugins include Anti-Spam, WP-SpamShield Anti-Spam and one I have been testing on some sites, Spam Destroyer. There are even some that use Google’s new “No Captcha reCaptcha” like this plugin Google’s No Captcha reCaptcha.
Use a Cloudflare
One of the best ways to keep spam off your website it to not let them get to your website in the first place. Some people dislike CLoudflare but it can help a great deal in reducing the automated spam from bots. You can even create a special page rule to protect the wp-comments-post.php file to increase the checks done no the people and bots trying to post a comment. This can make it much easier to keep the bots away and by even just making it a little slower to try and post a comment to your website.
