Spam can be very dangerous for website visitors as it is used to collect personal data which spammers then use at their discretion. Spam messages often contain links to third-party resources of cyber criminals. If you click on them, you can share some confidential information: logins, passwords, bank card number, ID data, etc. The presence of such spam in the comments of your site may damage the efficiency and reputation of your website. That is the reason why spam protection is required.

How to Organize Your Spam Protection?

The easiest way to protect the website from undesirable letters is to use various plugins. We suggest you get acquainted with some of them which can easily detect spam IP and blacklist it.

Of course, you can try to avoid the spam, using some simple methods, such as the disabling the comments function, restricting access, or even “captcha”. However, it is suitable only for non-profit, single-page, and landing sites. Users are more likely to leave feedback if they do not need to go through a long and boring process of verification. So when choosing a plugin, consider what methods it uses to verify data to make the site surfing as comfortable as possible.

In addition to spam in your site comments, your site may occur to be infected with a spam script. As a result, you can lose your reputation and get sanctions from searching services and it will not be available for visiting. That is why it is desirable to know that your site is “clean”. To find it out, you can use CleanTalk, which also provides the domain/IP checking of spam activity.
