  23. Now simply paste your key values into the configuration screen for the VouchSafe plugin, and select whether you want it to validate comments, user registration, or both, (we recommend both). If you wish, you can also edit the error messages that appear if a user fails to complete validation or submits a wrong answer.

All Done

And that’s it.  If you attempt to create a new user account or to leave a comment on a blog post, you should now see the VouchSafe button just above the submit button for the form.  If you click on the button, the VouchSafe challenge should appear with the color combinations you selected. In the picture shown here, we’re using the “gunmetal” interface with a black overlay.

Important Note: Security Issues Relating to WordPress

VouchSafe is an effective barrier to spammers IF users are required to interact with the VouchSafe validation. However, in developing a plugin, we can’t directly address issues relating to individual WordPress configurations, or the interaction between other plugins that users may or may not have installed in their particular website configuration.

There is an issue specific to WordPress, wherein spammers have learned that they can bypass form validation altogether by exploiting Trackbacks. You’ll know this is happening if you start to get spam without getting notifications of new messages – the spammers are simply bypassing the comment mechanism and any spam prevention system that you might have installed to validate input.

Not every WordPress template supports the trackback block, but if you experience difficulty with this issue, you have two choices:

  1. You can simply disable Trackbacks by selecting Settings -> Discussion in your administration console and unchecking the “Allow Link Notifications from other blogs (pingbacks and trackbacks)” option.
  2. disabling trackbacks in WordPress


  3. You can install a separate plugin created to address this particular WordPress issue. You can find that plugin in the WordPress plugins directory at this URL:
