Use third-party anti-spam systems

Hackers and painters mentioned the anti-spam algorithm: Bayesian algorithm. Many anti-spam systems are used. Therefore, you can try a third-party spam comment system named Akismet.

Akismet was developed by WordPress founder Matt Mullenweg. If your blog is built with WordPress, this function is already available.

Akismet has a powerful automatic learning function, which is much more powerful than simply setting several sensitive words.

If not, it does not matter. Akismet provides powerful APIs, and most systems such as CI and ZF have related modules and plug-ins.

In addition, NoSpamNX can also try to deal with robots.

Verification Code

More than 90% of spam comments are generated by robots. Therefore, you can use verification codes to filter out most spam comments.
