Best Free Spam Filters for WordPress

Spam on your website or blog comes in 2 forms,  computer spam and people spam.   You need to protect against both so you are going to need 2 plug ins.   Computer generated spam comes from automated programs that troll the web.  People spam is generated by humans.  Spammy sites use cheap labor to manually leave messages where bots fail.

After trying several spam filters which were advertised as “free” I was notified the “free” license expired and began looking for a truly free solution.


ReCAPTCHA protects against computer spam.  ReCAPTCHA originated at Carnegie Mellon University and was later acquired by Google.  Popular sites such as Facebook and Twitter use it.   reCAPTCHA works by creating images it the distorts so they can be read by a human but not easily by a computer program or by optical recognition programs.

BEST FREE SPAM FILTER:  Cookies for Comments

Cookies for Comments is designed to help protect your site against human spam mills.   Since there are spam filters that identify and block known spam mills, spammers are now setting up sites that do not accept cookies.  Cookies for Comments creates cookies that follow the person that is leaving a comment.

How Do I bulk delete spam in Word Press?

WordPress does not have an easy way to select multiple comments.  Each comment needs to be dealt with on a one on one basis.  If your spam has built up this could mean having to clean up hundreds if not thousands of spam comments.   I used plug in “Delete Pending Comments”.    Unless you want to take the time to make a decision on each individual comment, Delete Pending comments will clear out all of your comments so you can have a fresh start.
