It’s time for a CAPTCHA

Recently my MKTG 470 students have been asking how to reduce the number of requests for irrelevant (a.k.a. spammy) comments on their blog.  Now that their websites have been active for a few weeks, spammers are attempting to use their blogs as a means to advertise their assorted products.

The easiest workaround is a CAPTCHA.  A CAPTCHA provides a means to determine if a commenter is a person instead of a computer.

Try this exercise to install a CAPTCHA in WordPress.  My favorite is SI CAPTCHA Anti-Spam, but I would love your feedback on other CAPTCHAs or other tools to reduce the spammy comment attempts on blog posts.

  1. Hi Theresa,

    Consider trying our clickable, picture-based CAPTCHA alternative:

    Rather than forcing website visitors to decipher warped and distorted text, it simply asks them to click on specific pictures (e.g. “Click on the dog”). Much less frustrating for your website visitors than squinting to read illegible words. At the same time, it’s much more secure against bots than text-based CAPTCHAs.

    Also, your marketing class might be interested to learn that in the future it could be used as an advertising channel by displaying a few relevant, sponsored ad images within the CAPTCHA picture grid.

    Take a look at our WordPress plugin or our website and let us know what you think!
