Free CAPTCHA Install & Review Sync

I’m getting a steady flow of spam through the contact forms on

• https://www.thephotoboothteam.com.au/contact/
• https://illawarrasparkulars.com.au/contact-us/

so I need a free, reliable “human check” added to each. I’m not tied to Google reCAPTCHA, hCaptcha, or simple math—any cost-free alternative that blends cleanly with the sites is fine. The check should appear only on those two contact pages, leave the rest of the forms untouched, and keep the user experience smooth on mobile and desktop.

At the same time, the Google reviews carousel on thephotoboothteam.com.au has stopped refreshing. There are new reviews live in my Google Business profile, but the section on the site hasn’t pulled them in and no obvious error message is showing. Please track down the cause (API key, caching, plugin glitch—whatever it is) and restore automatic syncing so every new review appears without manual updates.

Deliverables
1. Spam-blocking human verification live and tested on both contact pages.
2. Google Reviews feed fixed and proven to auto-update with the latest entries.

Once you’re done, send a quick walkthrough of what was changed so I can maintain it going forward.
