Fortunately, WordPress offers thousands of anti-spam plugins that will check your site to ensure whether there are any comment spams or not and removes them from your website. With the help of anti-spam plugins, you can tighten the security of your site in minutes.
In this blog post, we will uncover the list of six most powerful anti-spam WordPress plugins that will help you protect your site from spammers and other security threats. But before this, let’s explore the key features of Anti-spam plugins:
Least Client side actions
Your client side actions should be kept as low as possible when a user enters some additional information other than writing the comment. An anti-spam plugin should not ask your genuine commenter to enter captcha for comments or to check/uncheck a checkbox as this could significantly affect the user experience of your site. So, your plugins must avoid such things when a genuine user comments on your site.
It is a filtration process that compares the client IP address of the incoming trackback with the IP address of the server. And if these two IP addresses don’t match, then it is a spam. So, always choose a plugin that can offer you the Trackback Validation functionality.
Block spam registrations
The WordPress registration page enables users to register on your site. The simplicity of the registration page allows automated spam bots to easily register on your site and post as many comments as possible. But you can block New User Registration spams by installing a great anti-spam plugin.
Minimum WordPress Database Impact
Choose an anti-spam plugin that enables the spam comment to be entered into the WordPress database. Once the comment enters in the database, the number of SQL transactions start decreasing, which automatically reduces the server load and improves the performance of the site (even during peak hours).
An anti-spam plugin should provide a statistics functionality to help you keep tracking and analyzing your data on a regular basis. It should provide weekly or at least monthly statistics of detected spam.
