WordPress Has A Built In Spam Blocker

Spam has become a huge issue across the board for virtually any platform. With all the spam there must be a way to control it. What most people don’t realize is that WordPress has it’s own built in spam blocker and they go out and pay for spam blocker plugins. Those paid for plugins might be needed if you’re site is huge, but if you are the average WordPress website owner chances are you don’t need something that robust. If you are looking for an affordable option that is easy to use then why not give WordPress’ already built in spam blocker a try, which works great.

The way I use it:

Login to your site’s dashboard and go to your “Comments” then click on “Pending”.

Open Notepad

Copy paste the text you want to block into Notepad (see images below)

Notice there is only one item per line of text. You can use URL’s, emails, or keywords here.

Next go to your “Settings” and click on “Discussion”. Scroll down to “Comment Blacklist” and copy / paste text from Notepad to that box and click the “Save Changes” button at the bottom of the page.

Additionally, you can just add keywords you want to ban. For instance I get tons of spam with drug names in them, but my site has nothing to do with drugs. It’s safe for me to assume that my readers will not comment about drugs on my site so it’s safe for me to go ahead and set up blocks to them now if I want to. Now, since the list of drugs is so long I haven’t done that, but just deal with them as they come, but the concept here is I could do it that way. I could just create a list like:

  • Adderall
  • Phentermine
  • Tramadol
  • Singulair
  • Drugs
  • Prescription


This will keep those comments out of my inbox and send them straight to spam. You can do this with any topic.

  • NFL
  • Purse
  • Abercrombie


The next time someone with that URL, email, or those specific keywords leave a comment on your website they will automatically go to your spam folder making getting through the important comments easier.

You can do the same thing for your “Comment Moderation” box. The same concept applies. Except instead of being sent to spam those comments are not approved, but held for moderation. I don’t use the “Comment Moderation” box as I moderate all comments because I don’t want to chance something horrible being posted on my site. I know some let all comments go, but I believe it’s my responsibility to protect my readers from obscene or useless content being posted. So all my comments are moderated, and when I’m moderating them I reply to those that I allow to be posted.

I hope this tip was helpful to you. I’d love to hear if you have any additional easy and free to use ways to moderate spam for our readers. Tell us in the comments below.
