If your comment box have spammed by someone, then try captcha. It’s a system that guard your site from any spam. Captcha will show up an image which is a handwriting text so machine or anything else wouldn’t read it. For wordpress just go to plugins and search for captcha and install it.

It require an API key to activate it. If you have done with that, check the result. If you want comment your post, then it should be appear below the comment box. Happy captcha-ing!
