Anti-bot Contact Form

After changing the Contact Us feature to a webform, we received an increasing number of spam submissions despite implementing a honeypot and CAPTCHA. The solution is to move the contact form to a new URL and override the footer hyperlink with a JS redirect.

1. Leave the Quick Links menu's "Contact Us" link as-is
2. Navigate to /admin/structure/webform/manage/contact_us/settings and change the Contact Us webform URL path to /contact-the-iac
3. Navigate to /admin/config/search/redirect
   • Enter "contact-us" in the search box, then click Filter
   • Select and delete all aliases
4. Navigate to /admin/structure/block/block-content and edit the Content Info block
   • Click on Source in the editor toolbar, then add the following HTML to the bottom of the block:
     <div id="b64path" hidden>L2NvbnRhY3QtdGhlLWlhYw==</div>
     (the L2N... string is Base64 encoding for "/contact-the-iac")
5. Edit the file $D9/themes/custom/iac_theme
   • Add the following line to the end of the "js:" section:
     assets/js/b64path.js: {}
6.  Create a new file in $D9/themes/custom/iac_theme/assets/js/b64path.js:
     $(document).ready(function () {
      $("a[href='/contact-us']").click(function(event) {
        window.location.href = atob($("div#b64path").html().replace(/^\s+|\s+$/g, "")), !1
        event.preventDefault();
      })
     })
7. Navigate to /admin/config/development/performance and click on the "Clear all caches" button
